COC material injection molding

COC material injection molding

(1) molding machine selection criteria: according to the product capacity to select the appropriate size of the molding machine. If the molding machine is too large, the residence time of the molten resin becomes long, and resin carbonization and yellowing tend to occur. (2) Screw design: The compression ratio should be about 2 lower, even if it is set to 2.5, it can be molded. When plasticizing, if the shear stress is large, the resin is prone to discoloration or mixing with black spots.

Analysis of the Properties of Cyclic Olefin Copolymer

Analysis of the Properties of Cyclic Olefin Copolymer

1, optical properties, because the COC material does not have a chromophoric group in the structure, for the light source that can stimulate quantum absorption shows excellent transparency. In the visible light range, the light transmittance of COC is equivalent to that of polymethyl methacrylate.

Polyisoprene latex has excellent performance and large space to replace natural latex

Polyisoprene latex has excellent performance and large space to replace natural latex

Polyisoprene latex is prepared from polyisoprene rubber, emulsifier, stabilizer and a small amount of antioxidant. It is a water-based emulsion of polyisoprene rubber. It has the characteristics of high tensile strength, high elongation at break, strong mechanical stability and chemical stability, and is not easy to cause skin allergy. It can be used in the production of surgical gloves, condoms, dental rubber barriers, physiotherapy tapes, catheter and other products. It can also be used as high-end adhesive and cold sealing adhesive for food packaging. At this stage, due to the high price of polyisoprene latex, it is mainly used for surgical gloves and other medical grade high-end medical and health products.
