High Impact Resistance PC Granules

High Impact Resistance PC Granules are modified polycarbonate compounds built to absorb mechanical energy and resist crack initiation at gates, notches, weld lines and assembled interfaces. Neat polycarbonate is naturally tough, yet under repeated drop testing, sharp impact or assembly stress it can still fail in a brittle way, especially around metal inserts and thin rib sections. This grade is formulated around a controlled impact-modification package that keeps the matrix ductile, so a shock is dissipated through plastic deformation instead of opening a crack that runs across the part. The practical effect for a molder is fewer cracked parts after drop or abuse testing and fewer warranty returns from end users who knock a housing against a wall or drop a handheld device. Buyers who source structural housings, lamp brackets and components that must survive transit, handling and everyday abuse get a material that flexes and gives on impact rather than splitting. The compound keeps polycarbonate's density of 1.2 g/cm3 and a heat deflection temperature at or above 135 C, and it is tuned to retain its toughness through the -40 C to +120 C service window that outdoor, under-hood and safety parts need. In glazing and safety-panel use, modified PC in this impact class has been reported to absorb well over 250 times the impact energy of glass of comparable thickness, and it breaks into blunt fragments rather than sharp shards, which is why it is favored wherever safety glazing logic matters.

On the production side, we run notched impact and drop-style checks through the compounding process so the impact modifier stays evenly dispersed and every lot lands inside the target toughness window. Because impact performance drifts quickly when dispersion is uneven, holding batch-to-batch values steady is what protects your molding yield and cuts the risk of field failures. We also look at gate design and rib thickness with you, since even the best impact grade will struggle at a poorly placed gate or a sharp internal corner. We supply samples that match mass-production quality before you commit to a run, so your first shots and your bulk orders behave the same way.

Handheld appliance housings (hair dryers, power tools). The ductile matrix survives repeated drops and knocks without cracking, which is exactly what handheld products live through in use.

Automotive lamp structural parts and brackets. It withstands road vibration, stone impact and thermal cycling while keeping the heat resistance the lamp assembly demands.

Transit and rail side windows, emergency escape panels. The shatter-resistant character absorbs impact and breaks into blunt fragments, meeting the safety logic of public transport glazing.

We adjust the impact level per your drop-test requirement, offer color matching, and can add flame retardancy on request. Custom formulations and packaging are developed against your own mechanical or drawing specifications.

Export packaging follows customer requirements and mutual agreement. We support EXW (buyer collects from the factory), FOB (we cover inland transport to the port and export clearance), and DDP (delivered duty paid to your warehouse).
