PET is the most widely used beverage packaging material today. Because PET can be conveniently obtained into amorphous, highly transparent and easily stretchable PET products through rapid cooling, when used as packaging material, PET can be made int...
Important Factors Affecting the Quality of PET Bottle Grade Chips Nowdays,PET is the most widely used beverage packaging material. Because PET can be conveniently cooled to get PET products which are basically in amorphous state, high transparency an...
Why are the specifications in ASTM D446, ISO 3105, IP 71, and BS important? Strict specifications and operating instructions for glass capillary viscometers are needed for the determination of kinematic viscosity of transparent and opaque Newtonian ...
Polyvinyl chloride (PVC for short) is a polymer formed by the polymerization of vinyl chloride monomer (VCM) under the action of initiators such as peroxides and azo compounds, or under light and heat according to the free radical polymerization mec...
Polyethylene (PE for short) is a thermoplastic resin obtained by the polymerization of ethylene. Industrially, it also includes copolymers of ethylene with small amounts of α-olefins. Polyethylene is odorless, non-toxic, and has a waxy feel. I...
In the research and development fields of polymers, polymeric materials, and pharmaceutical raw and auxiliary materials, viscosity is one of the key indicators for measuring product quality. The accuracy of viscosity measurement data has a decisive ...
