What is Polypropylene? Polypropylene (PP for short) is a semi-crystalline thermoplastic polymer made from propylene monomers through addition polymerization. It is usually a white waxy solid, non-toxic, odorless, transparent in appearance and light in texture. Its chemical formula is (C3H6)n,

What is LDPE? Low-density polyethylene, also known as high-pressure polyethylene (LDPE), is the lightest variety of polyethylene resin. It is milky white, tasteless, odorless, non-toxic, and matte waxy particles. It has good softness, extensibility, electrical insulation, transparency, easy processing, and

What is PVC? Polyvinyl chloride (PVC) is the third largest synthetic polymer plastic in the world (after polyethylene and polypropylene), with an annual production of about 40 million tons of PVC. PVC is a polymer formed by the free radical

What is HDPE? High-density polyethylene (HDPE) is a white powder or granular product. It is non-toxic, odorless, with a crystallinity of 80% to 90%, a softening point of 125 to 135°C, and an operating temperature of up to 100°C; its

PET Plastic? Natural PET is a transparent plastic with a glossy surface. It has all the advantages of glass – a strong, inert material that does not react with food. It resists attack by microorganisms such as bacteria, fungi and

Introduction to Plastics Plastics are a class of materials consisting of a variety of synthetic or semi-synthetic organic compounds that are ductile and can therefore be molded into solid objects. Plasticity is a universal property of all materials, i.e. the
