PVC Machining – PVC Fabrication
PVC Machining, PVC is a member of the family of copolymers and homopolymers. Being Produced in a wide range of forms: from clear thin versatile sheet utilized in seat covers, to rigid thick sheet utilized in corrosion resistant applications.

Sentinel Plastics Ltd deals solely in rigid-sheet PVC, a material that’s chemically non reactive, and can be machined to close tolerances and finishes.
PVC is the eldest sheet product within the marketplace. Notably used for corrosion resistant tanks, ducts, fume hoods, and pipe. Also, PVC possesses excellent electrical properties, outstanding chemical resistance, low moisture absorption, good dimensional strength, and good compressive strength. Once these properties are coupled with PVC’s flame resistance, and chemical bond ability. it’s easy to understand why PVC is thus often the material of choice within the corrosive resistant trade.
The chief drawbacks of PVC are poor weatherability, relatively low impact strength, and high weight for thermoplastic sheet. It’s easily scratched or tarnished, and possesses a relatively low heat distortion point.
Key Features: Good chemical resistance and is easily thermoformed. Very good electrical insulation.
Applications: Machined components, signage and prototype models. Chemical apparatus, plugs, tank linings, battery separators, insulators, signs, pallets, prototype models.
Hot Wire Forming PVC
As a general rule, PVC sheet can be safely heated up to 120°– 140°C and at this temperature behaves in a manner that enables it be formed into complex shapes with tight curves and deep draw. Hot line bending requires that the PVC sheets are softened along a narrow line by a strip heater, usually a hot wire.
