The difference between TPE and PP materials

Both TPE and PP are used to make plastic products, but many material buyers may not understand the safety of TPE or PP materials.The quality of material procurement directly affects the sales profit of finished products.With the improvement of living standard, most consumers will consider environmental protection and health issues when buying plastic products.

What is TPE?TPE material properties and application scope:

TPE, also known as Thermoplastic Elastomer, is a Thermoplastic Elastomer.Thermoplastic means that it can be recycled and molded.TPE products have excellent colorability, environmental protection non-toxic.It can be molded by injection twice, coated with PP, PE, PC, PS, ABS and other matrix materials, or molded separately.

TPE is less resistant to heat than rubber, and its physical properties decline with increasing temperature, thus limiting its scope of application.At the same time, compression deformation, elastic recovery, durability and the same as the poor rubber, the price is often higher than similar rubber.Wide range of hardness, excellent transparency, glossiness, and comfortable feel, widely used in adult products.With good uv resistance, weather resistance, high temperature resistance, long - term for outdoor.TPE is also a composite of many thermoplastic elastomers (TPEE, TPA, TPO, TPV, TPU)!


TPE is safe and non-toxic, and its environmental protection conforms to the environmental protection standards of European and American countries.Extensive processing methods, such as injection molding, extrusion, pouring, blow molding and other processing technology, comfortable texture, convenient surface, wide hardness range (0-100A), can be used repeatedly, the production process is safe and non-toxic!At present, China plastic TPE raw materials comply with FDA certification and LFGB standard, test report including ROHS, and EN713, REACH, PAHS, medical level certification, widely used in adult supplies, baby supplies, diving equipment, sports equipment and tools to handle, castor, massage insoles, ice boxes, dolls, toys, luggage accessories, electric cable, car accessories, stationery, environmental protection membrane, elastic tube, seals and other plastic products.

Properties and application range of PP material:

Polypropylene material is polypropylene, a plastic, it is a high density, no side chain, high crystal linear polymer, with excellent comprehensive properties!The main use of household water bottles, buckets, plastic bags, fast food boxes, drink bottles!


PP material has what characteristic, polypropylene is avirulent, odorless, tasteless milky white high crystalline polymer, it is at present all plastics one of the lightest variety.Polypropylene has good chemical stability.In addition to the concentrated sulfuric acid and nitric acid, the chemical reagent of polypropylene is relatively stable.But low molecular weight aliphatic, aromatic and chlorinated hydrocarbons can soften and expand polypropylene.At the same time, the chemical stability of polypropylene increases with increasing crystallinity, so polypropylene is appropriate.Production of various chemical pipes and accessories, good anti-corrosion effect.

Which material is safe, TPE or PP?

From an environmental point of view, polypropylene material is non-toxic, but TPE meets food grade standards, so TPE is safer than PP material, and TPE will become one of the preferred raw materials for the plastics industry in the future.
