Polypropylene anti-corrosion adhesive tape for household goods is very large in plastic, and the basic information we can contact with Chinese food is PP, usually with color, with pigments and masterbatches.

So in our daily life, what else are we made of polypropylene (PP)?

1. Pot, barrel, furniture, film, woven bag, bottle cap, car bumper.

2, disposable cup, jelly cup, plastic cup are polypropylene, generally opaque, add jelly cup polypropylene transparent masterbatch transparent.

3, PP packaging film is also a large variety. Tobacco film and the like are PP, the amount of large.

4. PP pipe, PPR pipe, etc.

5. Polypropylene anti-corrosion tape is used for corrosion protection equipment such as secondary processing.

6. Disposable sterile syringes and other medical devices.

7. Plastic trays and other trash large packaging and transportation supplies.

8, modified polypropylene anti-corrosion tape use is big, automotive technology, electrical development areas can be everywhere, mainly through flame retardant, reinforced, toughened, and so on.

Polypropylene Anticorrosive Tape-Introduction to Polypropylene

Polypropylene is a non-toxic, tasteless, tasteless Milky White high crystalline polymer, its density is only 0. 90-"0.91g/cm3, which is one of the very light varieties of all plastics. It is particularly stable for water, the water absorption rate is only 0. 01%, the molecular weight is about 80,015 million. The formability is good, but due to the shrinkage rate (1% ~ 2.5) is larger. Thick-walled products are easy to sag. For some high-size precision parts, it is difficult to meet the requirements, and the product surface gloss is better.

There are many friends who want to replace the blow molding tray, because they know less about the performance of its raw materials, so it is a lot of trouble. At present, the material used to make blow-molded pallets on the market is mainly high-density impact polypropylene.

The product performance of different raw materials is different. In order to control and improve the performance of plastic products on the market, a large number of modified raw materials are used. Today, Jinxiu also came to finishing, blow molding tray two kinds of raw materials summarized the advantages and disadvantages.

Polypropylene anti-corrosion tape (PP)

Advantages:

1, the elasticity is better than PE, can be bent repeatedly, good bending fatigue resistance.

2. It has good heat resistance and can be sterilized in high temperature environment.

Its chemical properties are stable, and many chemical reagents can be used normally when in contact.

4, high-frequency insulation material performance has excellent, almost no water absorption, so the insulation technology performance can not be affected by humidity and temperature.

Disadvantages:

1. Polypropylene anti-corrosion tape is easy to sag

2, not suitable for low temperature environment

3, not suitable for contact with copper products

It is also very sensitive to ultraviolet rays.

Why is the blow molding tray on the market now, the material often used is high-density impact-resistant polyethylene? Compared with polyethylene, its strength, impact resistance, and wear resistance have been greatly improved. More suitable for blow molding and injection molding.
