Bottle blowing machine factory tells you the names, advantages and disadvantages of common plastics for injection

advantage

1. The mechanical properties are better than any plastic material, and the heat resistance and weather resistance are very good.

Disadvantage

1. The water absorption rate is high, it should be dried before molding, and the dried material should not be exposed to the air for a long time.

2. The material is sensitive to stress and requires high precision for the mold. When designing the product, the wall thickness ratio of the product must be considered.

3. The product has high processing requirements, the machine must have a good clamping force, and the special material screw has poor fluidity.

Use

Mostly used for the production of electric toy casings, electrical casings, safety helmets, bulletproof glass and electrical components.

PP (one hundred percent glue)

Advantages

1. Have good fluidity and good molding performance.

2. The surface of the part is good, and the dyeing effect and trauma are better than polyethylene.

3. High heat-resistant plastic among general-purpose plastics.

4. High molecular weight, easy to crystallize, high tensile yield strength.

5. The surface of the product is good, and the dyeing effect and trauma are better than polyethylene.

6. High heat-resistant plastic among general-purpose plastics.

7. Good electrical performance, low density and resistance to stress cracking.

Disadvantage

1. Large shrinkage rate, difficult to control the size of the product.

2. Printing, pasting, plating and other processing difficulties.

3. Poor fire resistance and poor weather resistance.

4. The inner wall of the larger part is prone to vacuum.

5. High requirements for mold exhaust.

6. Insufficient rigidity and low notch strength.

Mechanical index

1. Heat-resistant temperature 135-150 degrees.

2. PP + 20% -40% talc, heat stabilizer, easy to flow, stable in size, used in engineering parts.

3.PP + 40% talcum powder, detergent, easy to flow, short cycle, used in washing machines and dry cleaning machines.

4. Organic acid resistant to 80 degrees.

5. PP + 10% talc powder, heat stabilizer, easy to flow, high gloss, used for small electrical appliances, auto parts.

6.PP + 30% -40% chemically coupled glass fiber, heat stabilizer, high rigidity, high strength, low shrinkage for engineering and automotive parts.

7.PP + flame retardant, anti-ultraviolet, easy to flow, weather resistant, mostly used for indoor and outdoor furniture.
