Polypropylene PP-FPC70T SABIC

SABIC® PP FPC70

1. PP is a semi-crystalline material. It is harder than PE and has a higher melting point. Since homopolymer PP is very brittle when the temperature is higher than 0℃, many commercial PP materials are random copolymers with 1 to 4% ethylene or clamp copolymers with higher ethylene content.

2. Copolymer PP material has lower thermal distortion temperature (100℃), higher transparency, low gloss, low rigidity, but has stronger impact strength. The impact strength of PP increases with the increase of ethylene content. The Vicat softening temperature of PP is 150°C. Due to the high crystallinity, the surface rigidity and scratch resistance of this material are very good.

3. PP does not have the problem of environmental stress cracking. Usually, the PP is modified by adding glass fiber, metal additives or thermoplastic rubber. The flow rate MFR of PP ranges from 1 to 40. PP materials with low MFR have better impact resistance but lower elongation strength. For materials with the same MFR, the impact strength of the copolymer type is higher than that of the homopolymer type.

4. Due to crystallization, the shrinkage rate of PP is quite high, generally 1.8~2.5%. And the direction uniformity of shrinkage is much better than that of PE-HD and other materials. Adding 30% of glass additives can reduce the shrinkage to 0.7%.

5. Both homopolymer and copolymer PP materials have excellent moisture absorption, acid and alkali corrosion resistance, and solubility resistance. However, it has no resistance to aromatic hydrocarbons (such as benzene) solvents, chlorinated hydrocarbons (carbon tetrachloride) solvents, etc. PP does not have oxidation resistance at high temperatures like PE.

6. PP plastic is polypropylene plastic, which is non-toxic and has no harm to the human body. Cups made of polypropylene are non-toxic, and the processing temperature (°C) during manufacture is 180-240. So boiling water will not decompose it. Therefore, there is no need to worry about the toxicity of the edible utensils.

Main performance

⒈Crystalline material, low hygroscopicity, easy to melt fracture, long-term contact with hot metal and easy to decompose.

⒉Good fluidity, but the shrinkage range and shrinkage value are large, and shrinkage holes, dents and deformation are easy to occur.

⒊The cooling speed is fast, the pouring system and the cooling system should slowly dissipate heat, and pay attention to controlling the molding temperature. The material temperature is low and the directionality is obvious. It is especially obvious at low temperature and high pressure. When the mold temperature is lower than 50 degrees, the plastic part is not smooth and easy to produce poor welding. , Leaving marks, warping and deformation may occur above 90 degrees

⒋The plastic wall thickness must be uniform to avoid lack of glue and sharp corners to prevent stress concentration.

Product Description
As part of the SABIC®PPFLOWPACT product portfolio, FPC70 has excellent stiffness/impact balance and can provide high load performance (potentially reduced performance). It has nucleation properties, good antistatic properties and easy demoulding. This grade has good flow properties and is specially designed for high-speed injection molding processes. It can achieve very cost-effective processing on the basis of simple mold filling and very short cycle times. Application: SABIC®PPFPC70 is generally used in rigid packaging applications in the food and non-food industries. This includes packaging for yellow fat, cheese sauce, dairy products, frozen, refrigerated and environmental foods, household chemicals and paints. It can also be used in a variety of applications for bottle caps and bottle caps and household products. . This grade has excellent heat distortion temperature and is especially suitable for hot filling applications. The product is not suitable for any pharmaceutical/medical applications, nor should it be used for any pharmaceutical/medical applications.
