What Is PC/ABS Alloy, and When Should You Choose It Over PC or ABS?
PC/ABS blends the impact strength and heat resistance of PC with the flow and cost profile of ABS. Understanding the trade-offs prevents costly material mistakes.

Applications and Innovation of Modified PP in Modern Industry
From automotive bumpers to compressor housings, the application envelope of modified polypropylene keeps expanding.
Polypropylene is one of the highest-volume commodity plastics in the world, but unmodified PP lacks the stiffness, heat resistance and low-temperature impact needed for structural parts. Compounding resolves that gap.
Talc filling (TD20/TD30) raises stiffness and heat resistance while controlling shrinkage; EPDM or POE toughening markedly improves low-temperature impact; glass fibre reinforcement pushes flexural modulus above 3,000 MPa, approaching some engineering plastics.
In automotive exterior trim, toughened systems such as PP+EPDM-T20 are now close to standard, while demand for flame retardant and weather resistant grades is growing clearly in appliances.
The key to specifying modified PP is to give the supplier the complete working conditions of the part — temperature range, load type, assembly method and weathering requirements — rather than just a resin abbreviation.
