What is the material of PP?
Polypropylene, a kind of plastic, is a high density, no side chain, high crystallization of linear polymer, with excellent comprehensive properties. Common products: basin, bucket, furniture, film, woven bag, bottle caps, car bumper, etc.
PP plastic, chemical name : Polypropylene (pp for short), proportion : 0.9-0.91 g/cubic centimeter, forming shrinkage rate :1.0-2.5%, molding temperature: 160-220℃. PP is a crystalline polymer, PP's comprehensive performance is better than PE material. Products made of PP have light weight, good toughness, and good chemical resistance. The disadvantages of PP: low dimensional accuracy, insufficient rigidity, poor weather resistance, it has a shrinkage phenomenon, it is easy aging, brittle, easy deformation after stripping. In daily life, the commonly used crisper is made of PP material.
Is PP material toxic?
To know whether pp material is toxic, we still have an accurate understanding of the nature of pp material first, the so-called pp material, that is, polypropylene in our daily life, it is a white translucent without side chain, high density linear polymer, has good oil resistance and weak acid and alkali resistance. Since its comprehensive performance is good, it is often used for household, bucket, basin, bottle cap and so on.
The main material of the inside pp is high purity propylene , which includes some small amount of ethylene copolymer. After drying, mixing, extrusion, granulation, screening and homogenization of polypropylene particles, this particle is cylindrical particles, particles are very smooth, without any mechanical impurities, it has good mechanical properties and heat resistance, It is not toxic when used in the temperature range of minus 30 degrees Celsius to 140 degrees Celsius.
PP material is a commonly used non-woven products, can be used in the production of face masks, protective clothing, isolation clothing, laboratory clothing, operating clothing, shoe covers, hats and other non-woven products. with the features of waterproof, moisture-proof, breathable, environmental protection, rich color and other characteristics.
PP material is a kind of environmental protection, non-toxic, automatic degradation of environmental protection materials, commonly used in medical, chemical, food, industrial, electronic and other industries.
