IR-30：
Liquid Isoprene Rubber
This product is a liquid isoprene rubber with a content greater than 99% and a molecular weight of approximately 30,000. Other components include residual solvents and anti-aging agents. The product is a viscous liquid at room temperature with a viscosity of about 60 Pa•s, appearing nearly transparent, light yellow, or yellow.
Product Characteristics:
Adding this product to natural rubber or other non-polar rubbers can produce pressure-sensitive adhesives, where this product can enhance the initial tack. Unlike commonly used tackifying resins, this product improves the initial tack of pressure-sensitive adhesives without significantly decreasing their holding power. Compared to degradable natural rubber, this product has higher thermal stability and lower odor. Compared to acrylic pressure-sensitive adhesives, this product has a lower glass transition temperature, making it suitable for various climates.

Liquid Isoprene Rubber
This product is a liquid isoprene rubber with a content greater than 99% and a molecular weight of approximately 50,000. Other components include residual solvents and anti-aging agents. The product is a viscous liquid at room temperature with a viscosity of about 500 Pa•s, appearing nearly transparent, light yellow, or yellow.
Product Characteristics:
By adding a small amount of this product during the rubber mixing process, it can partially replace some rubber while reducing the Mooney viscosity of the rubber, thus improving its processing performance. Since this product has a structure similar to natural rubber and can be vulcanized, adding a small amount will not weaken the rubber's strength like other substances such as aromatic oils, and it will not exude during long-term use. This product can also be used independently 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 "plasticizers," LIR is a high molecular weight rubber with plasticizing functions.
During the vulcanization process, LIR can co-vulcanize with sulfur or peroxides.
As a plasticizer & softener in rubber, it can improve the following properties:
Improved processing operability
Enhanced physical properties and processing performance of low-hardness rubber products
When used with white carbon black or clay, it can improve mechanical properties
When using LXIR, it can improve adhesion between metal materials and glass materials
Can co-vulcanize with NR, IR, IIR, SBR, BR, NBR, CR, EPDM, etc.
No migration in the products and no extraction in solvents, enhancing the aging resistance and chemical resistance of the products
Widely used in the tire industry, wires and cables, sealing strips, hoses, seals, printing & textile rollers, and other rubber products. It can also be applied in
adhesives, sealants, room temperature curing products, polyurethane material modification, coated products, asphalt modification, lubricant additives, and other industries.
