Material Selection Guide: Aluminum, Stainless Steel, and Titanium Alloy Comparison
Compare aluminum, stainless steel, and titanium for CNC machining. Analyze strength, weight, cost
Inherently flame-retardant and corrosion-resistant — economical and durable
PVC (polyvinyl chloride) is one of the highest-volume general-purpose plastics globally. Rigid PVC (UPVC) contains no plasticizers, offering high rigidity, natural flame retardancy (UL94 V-0), and resistance to most acids, alkalis, salts and oxidants.
PVC machines well, achieving smooth surfaces; transparent PVC can approach acrylic transparency after polishing. It has high notch sensitivity, requiring avoidance of sharp corners and stress concentration during processing.
PVC can be bonded with specialty adhesives or hot-air welded, facilitating fabrication of large chemical tanks, piping systems and clean equipment. We specialize in batch production, 100 pcs MOQ, lead time 15-25 days.
The following table lists typical mechanical, thermal, and physical properties for this material. Actual values may vary by grade and temper.
