IR-30:
Liquid Isoprene Rubber
This product is a liquid isoprene rubber with a content of more than 99%, a molecular weight of about 30,000. Other components include residual solvents and antioxidants. The product is a viscous liquid at room temperature with a viscosity of about 60Pa•s, nearly transparent in appearance, pale yellow or yellow.
Product Features:
Adding this product to natural rubber or other non-polar rubbers can produce pressure-sensitive adhesives, and this product can enhance the initial tackiness. Unlike commonly used tackifying resins, this product does not significantly reduce the cohesive strength of pressure-sensitive adhesives while improving the initial tackiness. Compared to degraded natural rubber, this product has higher heat stability and less odor. Compared to acrylic pressure-sensitive adhesives, this product has a lower glass transition temperature and is suitable for various climates.
IR-50
Liquid Isoprene Rubber
This product is a liquid isoprene rubber with a content of more than 99%, a molecular weight of about 50,000. Other components include residual solvents and antioxidants. The product is a viscous liquid at room temperature with a viscosity of about 500Pa•s, nearly transparent in appearance, pale yellow or yellow.
Product Features:
Adding a small amount of this product in the rubber compounding process can replace part of the rubber, while reducing the Mooney viscosity of the rubber, improving its processing performance. As this product has a structure similar to natural rubber and can be vulcanized, adding a small amount of this product will not reduce the strength of the rubber like other aromatic oils and will not exude over long-term use. This product can also be used alone as an adhesive, especially suitable for room temperature vulcanization systems.
LIR is a viscous liquid rubber developed based on isoprene.
LIR is colorless, transparent, and odorless.
LIR functions: reactive plasticizer & softener
From the perspective of "plasticizer," LIR is a high molecular weight rubber with plasticizing functions.
During vulcanization, LIR can be co-vulcanized with sulfur or peroxide.
When used as a plasticizer & softener in rubber, it can improve the following rubber properties:
Improves processing operability
Enhances physical and processing properties of low hardness rubber products
Improves mechanical properties when used with white carbon black or clay
Improves adhesion with metal materials and glass materials when using LXIR
Can be co-vulcanized with NR, IR, IIR, SBR, BR, NBR, CR, EPDM, etc.
No migration in products and no extraction in solvents, improving product aging and chemical resistance
Widely used in tire industry, wire and cable, sealing strips, hoses, seals, printing & textile rubber rollers, footwear and other rubber products. It can also be used in adhesives, sealants, room temperature cured products, polyurethane material modification, adhesive products, asphalt modification, lubricant additives and other industries.
