Introduction to EVA

Common Features When the vinyl acetate content of EVA is less than 20%, then it can be used as plastic. EVA has good low temperature resistance, its thermal decomposition temperature is low, about 230 °C, with the increase of molecular weight, the softening point of EVA rises, the machinability and the surface gloss of plastic […]

Dioctyl Terephthalate is an excellent environmental plasticizer

Dioctyl terephthalate (DOTP) is an organic compound with the formula C24H38O4. It is a transparent oily liquid, insoluble in water, soluble in general organic solvents. Dioctyl terephthalate is an excellent main plasticizer for polyvinyl chloride (PVC) plastics. Compared with the commonly used diisooctyl phthalate (DOP), it has the advantages of heat resistance, cold resistance, volatilization

Introduction to Polyethylene

Polyethylene (PE for short) is a thermoplastic resin made from ethylene through polymerization. In industry, it also includes ethylene and a small amount of α- Copolymers of olefins. Polyethylene is odorless, non-toxic, feels like wax, has excellent low temperature resistance (the minimum use temperature can reach – 100~- 70  °C), good chemical stability, and can

Classification of Polyethylene

Polyethylene can be divided into high density polyethylene (HDPE), low density polyethylene (LDPE) and linear low density polyethylene (LLDPE) according to the polymerization method, molecular weight and chain structure. LDPE Properties: tasteless, odorless, non-toxic, opalescent, waxy particles with a density of about 0.920 g/cm3 and a melting point of 130  °C~145  °C. Insoluble in water,

Characteristics of Polyethylene

General characteristics Polyethylene resin is non-toxic and tasteless white powder or particle, with milky white appearance, wax like feel, and low water absorption, less than 0.01%. The polyethylene film is transparent and decreases with the increase of crystallinity. The polyethylene film has low water permeability but high air permeability, so it is not suitable for
