PP Modified Series

Polypropylene is a widely used general-purpose plastic. Its main characteristics are low specific gravity, good rigid chemical stability, low water absorption and excellent high frequency performance, and its disadvantages are brittleness of products at low temperature, high molding shrinkage rate and low heat distortion temperature. Lijia Company enhances the performance of PP to a new level and gives products special purposes by adopting advanced formulas and equipments and using modified methods such as reinforcement, flame retardancy, toughening, transparency, high gloss, heat resistance, antistatic measure.

Performance and application of typical products:

Material Grade Characteristics Typical Applications
General-purpose PP AB132 High gloss & high flow Shell of household appliances such as rice cooker, microwave oven & coffee pot
BT100 Heat resistance & high gloss Kitchen utensils & packaging products
AF112 Environment-friendly flame retardancy & high flow Bobbin, electrical housing, electrical switch, connector & microwave components
AF189 Halogen-free flame retardancy & high flow Electrical and electronic components

(Note: products of special specifications and colors may be developed according to different requirements of customers.)
