PET is the height of milky white or light yellow crystalline polymer, surface smooth and glossy. Resistance to creep, fatigue resistance, friction resistance and good dimensional stability, wear small, high hardness, has the largest of thermoplastics toughness: electric insulation performance is good, affected by temperature is small, but the plastic cosmetic tubes corona resistance is poor. Non-toxic, good weather resistance, chemical resistance stability, bibulous rate is low, resistance to dilute acid and organic solvents, but not hot water immersion, not alkali resistance. PET resin of high glass transition temperature, crystallization speed is slow, the molding cycle is long, the molding cycle is long, the molding shrinkage rate, poor dimensional stability, crystallization of forming a brittleness, low heat resistance.

Pet polyester bottle, with its texture is lighter, high transparency, hockey, compressive strength and impact resistance should not be broken, and other products advantages, in various fields has been widely recognized and cosmetic tube packaging applied. However, pet polyester bottle what product performance you know? For more than ten years has focused on plastic industry manufacturers of plastic small make up to share the product performance of pet polyester bottle.

A: the general performance: PET resin for the milky white or colorless transparent body, relatively low density, high light transmittance. PET belongs to medium barrier property material with absorbent.

2: mechanical properties, tensile strength, abrasion resistance and frictional resistance, good mechanical properties affected by the outside temperature is smaller.

Three: electrical performance: has excellent electrical insulation, can remain under high frequency, small electrical property affected by temperature, humidity influence.

Four: the oxidation resistance, excellent oxidation resistance, can be suitable for outdoor use.

Five: transparency: the transparency of pet polyester bottle is higher than other material plastic bottles.

PET plastic bottle appearance is neat, bottle face is very tube lip gloss smooth, thread is complete, no damage, and its crystallinity is very good, no good material conditions, also won't have any reel off raw silk from cocoons. The plastic bottles are not deformation, also there is no oil inside. Bottle forming degree is very good, transparency is very high, also did not appear black spots, scratches, atomization, pale, hardening of the metal cosmetic tubes phenomenon, colored bottles should be color is more uniform, no clear off color.

The bottom of the bottle is no sag, and also does not have prominent place, at the bottom of the bottle does not appear rupture phenomenon, no delamination phenomenon. Composed of blow molding processing transparent small plastic bottle, now we see more and more on the market. From food packaging to cosmetics packaging and beverage packaging, we have seen more and more transparent plastic bottles on the market.
