Testing & Analysis

Our experts have extensive background in all areas of plastics, meaning they can research, test, and report the vital facts in any litigation involving the failure of plastic materials including PVC, CPVC, Nylon, PP, PE, PS, PC, PET, rubber, coatings, adhesives, and composite materials.

Product Design

Plastic parts often fail because they weren't properly designed. Concentrated mechanical stresses that aren't distributed evenly across the part can cause it to fail. We specialize in successfully designing and manufacturing plastic products efficiently and safely using the best material for the application.

Manufacturing & Consulting

We provide detailed consultations on the safety of existing plastic infrastructure like piping, and offer recommendations when upgrades are needed to help employers and manufacturers avoid liability due to work-related accidents from dated materials.
