Dalian blown film machine factory introduction to common plastic material, low density polyethylene

Low density polyethylene degrees polyethylene (LDPE) is a kind of plastic material, it is suitable for thermoplastic processing a variety of molding process, forming good workability.LDPE main purpose is for thin film product, also used in plastic injection products, medical devices, pharmaceutical and food packaging materials, hollow blow molding products, etc.Low density polyethylene what point?Blown film machineSet factory details for you:

Non-toxic, tasteless, small density, strength, stiffness, are better than that of low pressure polyethylene, hardness and heat resistance can be used at about 100 ℃.Has good dielectric properties and high frequency insulation and is not affected by humidity, but low temperature time-varying crisp, wear-resisting, easy to aging.Suitable for making general machinery parts, corrosion parts and insulation parts.Common acid, alkali and other organic solvents almost had no effect on it, it can be used in tableware.

Polypropylene has many excellent features:

1, the relative density is small, only 0.89-0.91, is one of the lightest varieties of plastics.

2, chemical performance is good, almost no water absorption, and does not react with most chemicals.

3, has higher heat resistance, continuous use temperature can reach 110-110 ℃.

4, good electrical insulation.

5, texture, pure, non-toxic.

6, good mechanical properties, in addition to the resistance to impact and other mechanical properties are better than polyethylene, processing performance is good.

7, the transparence of polypropylene products better than transparency of high density polyethylene products.

It has many advantages but also disadvantages:

1, easy to burn.

2, products in the use of easy by light, heat and oxygen and the effect of aging.

3, color is not good.

4, toughness is bad, electrostatic degree is high, dyeing, printing and binding.

5, poor products cold resistance, low temperature impact strength is low.

PP don't like PE still has the oxidation resistance at high temperature.In the general industrial use of glass fiber reinforced polypropylene fiber containing 10-30%.Due to containing glass fiber has good heat resistance and dimensional stability.Reinforced pp is mainly used in the manufacture of all kinds of machinery parts, mainly including car fan, air-conditioning fan, water purifier filter bottle, in the electronics industry can be used in all kinds of household appliances appearance instead of ABS, HIPS, widely used in refrigerator lid, air conditioning base, foot bath, etc.
