BJ350 / high stiffness Impact / PP Samsung Total purposes: crates, furniture, toys, tool boxes, containers, electronic components features Note: High stiffness, impact copolymer injection Important parameters: melt flow rate: 5 g / 10min density: 0.91 g / cm3 notched impact strength: 11 Tensile strength: 39 MPa Elongation at break: 300% flexural modulus: 1422 MPa Hardness: 85 thermal deformation temperature: 110 ℃ Manufacturer: Samsung Total Company Limited PP plastic Chemical name: Polypropylene English name: Polypropylene (abbreviated PP) Gravity: 0.9-0.91 grams / cubic centimeter molding shrinkage: 1.0-2.5% molding temperature: 160-220 ℃. Heat distortion temperature of 80-100 ℃, a high flexural fatigue resistance, commonly known as "pleated plastic." PE ratio transparent, non-toxic, tasteless, can be used for utensils. Low density, good toughness, good chemical resistance. PP drawbacks: low dimensional accuracy, lack of rigidity, poor weather, easy to produce "copper harm", after a contraction phenomenon, after stripping, easy to aging, brittle, easily deformed. PP polypropylene can be filled, enhancement, blending, copolymerization, crosslinking modification. Such as calcium carbonate. Talc, etc. inorganic mineral filler, can improve the rigidity, hardness, heat resistance and dimensional stability; add glass fibers, asbestos fibers, mica, glass beads, etc. can improve the tensile strength, and improved creep resistance, low temperature impact; adding elastomer and rubber may improve impact resistance, transparency, etc. PP (polypropylene) according to the performance can be classified as: homo grade PP, copolymer grade PP, transparent grade PP, weathering grade PP, high impact PP, antistatic PP, high flow PP, fire-retardant PP, high hardness PP, cold PP, blow molding (bottles) PP, film (transparent) PP, BOPP (biaxially stretched) PP, board-level PP, high heat PP, medical grade PP, food grade (FDA) PP, glass fiber reinforced PP, mineral fiber reinforced PP, high gloss PP, low warpage PP, hydrolysis PP, PP high elongation and so our long-term cash to provide the above-mentioned corresponding PP polypropylene products, Welcome to contact us ......
