Manufacturer identifies cosmetic tube materials

1, cosmetic plastic TUBE PP === 100 fold glue, polypropylene is light and tough, easy to process, good heat resistance,. High impact strength at normal temperature, high tensile strength, good rigidity, corrosion, difficult to paint, folding resistance up to millions of times, excellent electrical function, large shrinkage rate. The PPP. E. PA is soft and bendable, with hard waxy touch and smooth feeling, and soft horny sound when hitting, while PS. ABS. The PC. PMMA, no ductility, loud percussion sound. PP incineration phenomenon and PE roughly the same, there may be a small amount of black submerged, the flame quelled, smell is between kerosene and other oil smell, non-toxic. 2, cosmetic plastic TUBELDPE === soft glue, high pressure low density polyethylene HDPE=== hard soft glue, low pressure high density polyethylene VHDPE== super hard soft glue, ultra-high pressure polyethylene is light and tough. Easy to process, good heat resistance, low temperature toughness is good hard impermeable, but good grinding, PE flammable, from the fire can still be burned, burning the flame on the yellow and blue, black submerged very little, near the flame, plastic melt dripping phenomenon, similar to the flow of the candle, the flame calm down, there is a more obvious burning smell of white wax, non-toxic PE. PP specific gravity is less than water, floating in water. Most other plastics are heavier than water and sink in water.

3, cosmetic plastic tubePC = = = bulletproof glue, polycarbonate colorless lit, the impact strength of rubber, plastic, electrical function is excellent, anti-aging, small shrinkage rate, dimension stability, PC burning phenomenon near the PS but burning speed is slow, away from the fire will burn slowly and after flame yellow, with black Yan charcoal beam, burning melt foaming, calm the coma is flowers and smelly.

4, cosmetic plastic TUBEPMMA === Plexiglas (sub-afterforce) polymethyl methacrylate clarity is very good, can be dyed into a variety of colors, brittle and easy to crack, poor hardness, easy to wipe flowers. Good resistance to leakage. PMMA and PS primary color are bright, but the burning situation is different, PMMA no carbon beam fly away, and PS is, PMMA burning flame is light blue, white top, burning when melting foaming, announced strong fruit odor and rotten vegetable odor, there is emblem poison.

5, cosmetic plastic TUBEPS === hard glue (general hard glue), polystyrene, transparent brittle crack HIPS=== not broken glue, modified polystyrene, elastic. Toughness and high impact strength ABS===ABS adhesive. Super non - broken adhesive, acrylonitrile - butadiene - styrene, easy to electroplate. High strength. Resistance to impact, cold, abrasion and corrosion. SAN (AS) === Ming not broken glue, styrene-propylene copolymer EPS=== foam glue, foamed polystyrene PS primary color is bright color, HIPS primary color is milky white, ABS primary color is light ivory color. PS. HIPS. The main difference between ABS is that PS is more brittle, HIPS and ABS have better toughness. When bending the sample, PS is easy to crack, HIPS and ABS are difficult to break, and the bending part is white. PS primary color is bright color, HIPS primary color is milky white, ABS is light tooth color. PS. HIPS. And ABS are flammable, take can still continue to burn after the fire, flame, yellow, and with black Yan charcoal beam, along with the Yan gas escape, PS less carbon beam, when burned, near the flame softening plastic appearance and is not easy to drop, the bubbles of PS and HIPS appearance, ABS no bubbles and the coking status, these plastic at calm announced that the smell of the difference is very big, PS with styrene monomer will, ABS announces a pungent odor, has certain toxicity.
