srg plastics specializes in custom plastic profile extrusion
Plastic profile extrusion produces a part that has a continuous
cross-section such as a tube or channel. Using heat up to 600
degrees F and pressure the profile is pulled at a specified line
speed through a machined set of dies and calibrators that
match the part dimensions.

Profile extrusion materials offered
- PVC available in rigid, semi-rigid and flexible (often referred to as vinyl)
- Acrylic excellent clarity and hardness used in retail display
- ABS considered an engineering grade exhibits good impact properties
- Polycarbonate has excellent strength (usually referred to as Lexan)
- Styrene is an economical choice for clear applications
- Polyethylene excellent impact strength and lubricity
- Polypropylene good durability and used in toys and consumer items
- PETG similar to acrylic and not as prone to fracturing
- TPE and TPR elastomers that exhibit natural rubber
