PA6

Full Name :

Styrene Butadiene Rubber

Description :

Polyamide 6, Nylon 6, or polycaprolactam (PA6) is one of the major engineering thermoplastics. PA6 is tough, has excellent abrasion resistance, good chemical resistance, fatigue endurance, lubricity, impact strength, high strength, and rigidity.

PVC

Full Name :

Polyvinyl chloride

Description :

Polyvinyl Chloride (PVC or Vinyl) is a high strength thermoplastic material widely used in applications, such as pipes, medical devices, wire and cable insulation...the list is endless. It is the world's third-most widely produced synthetic plastic polymer. So, what is PVC? What is it made up of? How to process it? Get detailed technical information on Polyvinyl Chloride and its features.

SBR

Full Name :

Styrene Butadiene Rubber

Description :

Styrene butadiene rubber (SBR) is one of the cheaper synthetic general purpose elastomers that is sometimes used as a substitute for natural rubber (NR). It can be produced by free-radical solution polymerization or by emulsion polymerization either warm at 30 to 60°C (hot rubber) or cold at temperatures near 0°C (cold rubber). Emulsion SBR (ESBR) continues to lose ground to solution SBR (SSBR) which is better suited for high-performance tires. Nevertheless, emulsion SBR grades still account for more than 75% of the total world capacity as of 2015. However, more and more SBR is produced by solution polymerization.

GENERAL PURPOSE

Full Name :

General Purpose Silicone

Description :

A silicone or polysiloxane is a polymer made up of siloxane They are typically colorless oils or rubber-like substances. Silicones are used in sealants, adhesives, lubricants, medicine, cooking utensils, thermal insulation, and electrical insulation. Some common forms include silicone oil, silicone grease, silicone rubber, silicone resin, and silicone caulk.
