- The Brazilian rubber tree, Hevea brasiliensis, is a member of the euphorbia family native to the Amazon Basin and accounts for 90% of all natural rubber. The Brazilian rubbertree is currently the only economic source of natural rubber among more than 2,000 plant species known to generate it.
- Due to a scarcity of natural rubber during World War II, scientists in the United States attempted to convert the latex of common milkweed into a rubber-like replacement.
- Asclepias syriaca, or commonmilkweed, is a native of North America and one of the most important northern plants for monarch butterflies.
- Due to a toxic alkaloid in the latex, monarch caterpillars and butterflies are bitter and harmful to birds.
- Viceroy butterflies look and act like monarch butterflies, but they are not toxic. Both species of birds are frequently avoided by birds.
- In humans, milkweed latex can cause dermatitis in those who are susceptible. Native Americans, on the other hand, employed this latex to remove corns and calluses.
What do we get from rubber plants?
Because the milky latex derived from this tree is the principal source of natural rubber, Havea brasiliensis is the most economically important member of the genus Hevea. The latex is a resin that the plant does not require. As a result, a plant waste product is extremely beneficial to humans.
Robusta
The hardy ficus elastica variant ‘Robusta’ has leathery big green foliage. It grows to a good height of 4-6 feet and can readily resist low humidity indoors.
Burgundy
The crimson stems of ‘Burgundy’ have rich, thick, burgundy to almost black leaves, as the name suggests. For the greatest foliage color, give it enough of light and humidity.
Yellow Gem
The leathery, green-centered leaves of this striking rubber plant have a golden-green hue towards the edges. It’s simple to grow and looks fantastic in big pots.
Where are rubber plants found?
Hevea brasiliensis is a rubberwood species native to the Amazon jungles of South America, which include Brazil, Venezuela, Ecuador, Colombia, Peru, and Bolivia. Low-altitude moist forests, wetlands, riparian zones, forest gaps, and disturbed regions are all common places to find these trees. It is a fast-growing tree that is often the first to establish itself when a canopy opening occurs, but it may be shaded out as more trees fill in the gap. Rubber that is economically produced may now be found across much of Southeast Asia and Western Africa.
What are the types of natural rubber?
Rubber, as we all know, is pliable. Not simply in terms of its mechanical qualities, which are elastic and bendable. Because rubber’s chemical features make it ideal for creating a wide range of synthetic rubbers that combine the best qualities of natural rubber with a slew of additional benefits.
We’ll look at ten of the most common types of rubber on the market today.
Natural Rubber (NR)
Isoprene (natural rubber) is made from the latex sap of the Pará rubber tree (hevea brasiliensis). Natural rubber has a high tensile strength and is resistant to wear from chipping, cutting, and ripping. Natural rubber, on the other hand, is only moderately resistant to heat, light, and ozone. Gaskets, seals, shock mounts, hoses, and tubing are all made of natural rubber.
Styrene-butadiene rubber (SBR)
Styrene-butadiene rubber is a low-cost synthetic rubber with great tensile strength, strong abrasion resistance, and outstanding impact strength. SBR, on the other hand, has a low resistance to UV, ozone, steam, and oils. Tyres and tyre products, automobile parts, and mechanical rubber goods are among the most common uses for styrene butadiene rubber.
Butyl (IIR)
For shock absorption, butyl rubber is an excellent choice. It has high resistance to heat, aging, weather, ozone, chemical attack, flexing, abrasion, and ripping, as well as excellent gas and moisture permeability. Butyl has high electrical insulating qualities and is resistant to phosphate ester-based hydraulic fluids. During production, it has a tendency to trap air, blister, and creep. O-rings, tank liners, and sealants are all common uses. Butyl is good for vacuum seals because of its gas impermeability.
Nitrile (NBR)
Nitrile (also known as NBR rubber or Buna-N) is the most extensively utilized and cost-effective elastomer in the seal business. This is due to its remarkable resistance to petroleum-based lubricants, fuels, water, alcohols, silicone greases, and hydraulic fluids, among other things. Nitrile is a thermoplastic with a temperature range of -54 to +149 degrees Celsius and a good balance of desirable features such as low compression set, strong abrasion resistance, and high tensile strength. It should not be used with automobile brake fluid, ketones, phosphate ester hydraulic fluids, nitro or halogenated hydrocarbons, or nitro or halogenated hydrocarbons.
Neoprene (CR)
Neoprene, a general-purpose elastomer, is unique in that it is fairly resistant to petroleum liquids and the elements (ozone, UV, oxygen). As a result, it is uniquely qualified for a variety of sealing applications in which many other materials would fail. It has a low compression set, strong abrasion and abrasion resistance, and is flex crack resistant. Neoprene and nitrile have the same operating temperature range, and it’s often used to seal refrigerants in air conditioners and refrigerators.
Ethylene Propylene Diene Monomer (EPDM)
EPDM rubber is a flexible rubber that resists heat, ozone, corrosion, and aging while also having low electrical conductivity, low compression set, and low temperature qualities. EPDM is a cost-effective alternative to silicone that, when put properly, can endure a long time before becoming embrittled. EPDM rubber can be found in a variety of HVAC and automotive applications, as well as in O-rings and electrical insulation.
Silicone (Q)
Silicone is a versatile material that works well with water, steam, and petroleum-based fluids. Silicone has been demonstrated to tolerate short exposures to temperatures as low as -115 degrees Celsius, despite its temperature range of -84 to +232 degrees Celsius. Silicone has weak tear resistance, abrasion resistance, and tensile strength, making it better suited to static applications than than dynamic ones. Silicone’s chemical stability allows it to be utilized in a variety of applications, including food and beverage, medicinal, sealants, lubricants, and circuit boards, to mention a few.
Viton (FKM)
Viton is a fluoroelastomer that can be used in a wide range of applications. This strong synthetic rubber and fluoropolymer elastomer, a DuPont trademark name, has high temperature stability ranging from -20 to +205 degrees Celsius. Viton has the disadvantages of swelling in fluorinated solvents, being very expensive, and failing quickly if the wrong grade is employed. It is one of the most frequent elastomers used for sealing applications, such as O-rings, gaskets, and seals, alongside nitrile.
Polyurethane (AU)
Polyurethane is known for its outstanding abrasion and extrusion resistance, as well as its overall toughness. Polyurethane O-rings would not be appropriate for applications demanding high compression and heat resistance. The latter is owing to a more restricted operating temperature range of -54 to +100 degrees Celsius. Hydraulic fittings, cylinders, valves, and pneumatic tools all require polyurethane O-rings.
Hydrogenated Nitrile (HNBR)
Hydrogenated nitrile rubber compounds outperform nitrile rubbers in terms of oil and chemical resistance, as well as being able to handle significantly higher temperatures. HNBR is resistant to oils, fuels, a variety of chemicals, steam, and ozone. It has high tensile and rip strength, as well as elongation and abrasion resistance. HNBR, on the other hand, is rather expensive, has poor electrical insulation, and is incompatible with aromatic oils and polar organic solvents. HNBR is commonly utilized in the automobile sector for a variety of components such as static seals, hoses, and belts, to mention a few.
Where are rubber grown in India?
Kerala and Tamil Nadu, the traditional rubber-growing states, account for 81 percent of production. The North Eastern states of Tripura, Assam, and Meghalaya, as well as Odisha, Karnataka, Maharashtra, and West Bengal, are major non-traditional rubber growing regions.
Is rubber plant good for home?
According to Vastu, rubber plants are the best and easiest-to-care-for houseplants, and they are specifically mentioned in the Vastu Shastra. It is well recognized to improve indoor air quality, as NASA tests have demonstrated. The rubber plant’s huge leaves can absorb and break down airborne pollutants and microorganisms, rendering them harmless to your health. In addition, the rubber plant takes exhaled carbon dioxide and turns it into safe and healthy oxygen for humans to breathe in. If you have a rubber plant in your room, mold spores and germs are also removed from the air. According to Vastu, the rubber plant has several benefits and should be included in your house decor.
Is rubber plant an indoor plant?
Ficus elastica is a tropical evergreen tree that can be found in southern China, Southeast Asia, and Indonesia. It is a member of the Moraceae family of plants, and its latex sap was used to create rubber until synthetics became accessible. Hevea brasiliensis, on the other hand, produces the majority of natural rubber. Although many plants contain significant levels of isoprene, the latexy sap of these two plants has enough to be used to create rubber.
F. elastica roots are used to build live bridges in tropical Northeastern India, in addition to being helpful for rubber! The F. elastica roots are led along a dead tree trunk that has been placed over a river. The roots grow to the other side of the trunk as it rots, thickening and training new roots to complete the bridge. Because it is flexible, the bridge can withstand strong winds and flooding. This tree is very stretchy in more ways than one! Rubber trees are ideal houseplants since they are low-light tolerant and assist to purify the air.
Moraceae is a plant family that includes shrubs, trees, and lianas that all leak a latexy sap when wounded. Foliar polymorphisms are found in members of this family, which means that their leaf forms vary depending on their life stage. Most other plants produce the same leaf forms throughout their lifetimes, thus this is a peculiar trait.
Can tolerate bright direct light and thrives in medium to bright indirect light.
Allow the soil to dry out between waterings. Water every 1-2 weeks. Increase the frequency as the light level rises.
Over time, this plant will grow to a maximum height of around 30′ (10m) with a spread of about 10″ (3.2m). As a houseplant, however, it will be much smaller.
It’s a plant that’s generally laid-back. Scale and mealybugs are possible. Scale bugs and mealybugs can be treated with weekly horticultural (Neem) oil sprays and regular wipe-downs of the plant as soon as they develop.
If eaten, this plant is poisonous to cats, dogs, and humans. Houseplants should always be kept out of reach of little children and dogs.
