Information

1、Cosmetic plastic hose PP===Polypropylene, polypropylene

 

  Lightweight, tough, easy to process, and good in heat resistance. High impact strength at room temperature, high tensile strength, good rigidity, corrosion, difficult to paint, folding resistance up to millions of times, excellent electrical function, large shrinkage rate. PPP. E. PA is soft and bendable, it has a hard waxy feel to the touch, and a slippery feel. It has a soft, horny sound when it hits it, while PS. ABS. PC. PMMA has no ductility, and the percussive sound is louder. The burning phenomenon of PP is roughly the same as that of PE. There may be a small amount of black ash. After the flame subsides, the smell of oil is between kerosene and the like, which is non-toxic.

 

  2、Cosmetic plastic hose LDPE===Soft rubber, high pressure low density polyethylene

 

  HDPE===Hard soft rubber, low pressure high density polyethylene

  VHDPE===Super hard soft rubber, ultra high pressure polyethylene

 

  Lightweight and tough. Easy to process, good heat resistance, good low-temperature toughness, harder and impervious to water, but good abrasiveness, PE is flammable, and can be burned after leaving the fire. When burning, the flame is yellow and blue, and there is very little black. Plastic has the phenomenon of melting and dripping, which is similar to the flow of candles. After the flame has subsided, there will be a more obvious burning smell of white wax, non-toxic PE. The specific gravity of pp is less than water and floats on water. The vast majority of other plastics have a larger specific gravity than water and sink into water.

 

  3、Cosmetic plastic hose PC===Bulletproof rubber, polycarbonate

 

  Colorless and transparent, the impact strength is the first of plastics, excellent electrical function, anti-aging, low shrinkage, product size is stable, PC incineration phenomenon is close to PS, but the incineration speed is slow, after leaving the fire, it will slowly extinguish, the flame is yellow, with black The charcoal beam melts and foams when it is burned, and when it subsides, it smells like flowers and fruits.

 

  4、Cosmetic plastic hose PMMA===Plexiglass (Acrylic)

 

  Polymethyl methacrylate has excellent transparency, can be dyed into various colors, is brittle and easy to crack, has poor appearance hardness, and is easy to scratch. Good leakage resistance. The primary colors of PMMA and PS are bright, but the burning conditions are different. PMMA does not have carbon beams to escape, while PS does. When PMMA is burned, the flame is light blue and the top is white. Stinky, with emblem poison.

 

  5, cosmetic plastic hose< /a>PS===Hard rubber (general hard rubber), polystyrene, clear and brittle

 

  HIPS===No broken glue, modified polystyrene, elastic. Toughness and high impact strength

 

  ABS===ABS glue. Super glue-free, acrylonitrile-butadiene-styrene, easy to electroplating. high strength. Resistant to impact, cold, abrasion and corrosion.

 

  SAN (AS)===transparent non-shattered, styrene-acrylonitrile copolymer

 

  EPS===Styrofoam, expanded polystyrene

 

  PS primary color is bright color, HIPS primary color is milky white, ABS primary color is light ivory.

 

  PS. HIPS. The main difference between ABS is: PS is more brittle, HIPS and ABS have better toughness. When bending the sample, PS is easy to be brittle, HIPS and ABS are difficult to break, and the bending part is white. PS primary color is transparent, HIPS primary color is milky white, ABS is light tooth color. PS. HIPS. Both ABS and ABS are flammable and can continue to burn after removing the fire source. The flame is yellow with thick black charcoal beams, which escape with the gas. PS charcoal beams are slightly less. When burned, the plastic surface near the flame softens It is not easy to drip. PS and HIPS will foam on the surface. ABS will not foam but will be in a coked state. The odors announced by these plastics are very different when they die. PS monomers with styrene will, ABS announces a kind of thorn The smell of the nose must be toxic.
