What is polyamide 12? also called Nylon 12 PHYSICAL & MECHANICAL PROPERTIES Polyamide 12, or also called Nylon 12, is an amorphous and transparent thermoplastic made from amino-lauric acid or laurolactam monomers that each have 12 carbons. It is manufactured and sold, among other, by the company EMS-Grivory under the name Grilamid TR. The main […]

What is silicone ? Liquid Silicone Rubber (LSR) PHYSICAL & MECHANICAL PROPERTIES Silicone Rubber is an elastomer composed of silicone—itself a polymer—containing silicon together with carbon, hydrogen, and oxygen. In its uncured state, silicone rubber is a highly-adhesive gel or liquid. In order to convert to a solid, it must be cured, vulcanized, or catalyzed. […]

What is O-PET (OKP-4) ? Optical polyester PHYSICAL & MECHANICAL PROPERTIES Osaka Gas Co. Ltd and Kanebo Ltd have co-developed an amorphous polyester material, OKP-4. It is now available commercially from Osaka Gas Chemical. The characteristics of OKP-4 are as follows: High refractive index (>1.6) Low birefringence Having a slightly lower transmittance value (90 % […]

What is COP (Zeonex) ? Cycloolefin polymer PHYSICAL & MECHANICAL PROPERTIES Recently COP, which was originally developed around 1990, has been used as an optical material for parts that require high quality. COP is a polymer with an alicyclic structure synthesized using a cycloolefin as a monomer. Its main chain has a bulky cyclic structure. […]

What is PMMA? Poly-methyl Methacrylate PHYSICAL & MECHANICAL PROPERTIES PMMA is especially known for its exceptional optical properties. This uncrystallized polymer shows remarkable transparency (92% light transmission) in the visible range from 380 to 780 nm. The angle of total reflection on an inner surface is 41 to 42° (which allows it to be used […]

What is polycarbonate ? PC Properties PHYSICAL & MECHANICAL PROPERTIES Polycarbonate is a polymer which, when uncrystallized, has excellent transparency. When thick, it has a slight yellowish tint. The index of refraction of transparent and colorless PC is very high, 1.584. The industrial grades of PC have molecular weights on the order of 20,000 to […]
