Working with PVC-P HT105
Is PVC-P easy to machine?
Machinable but gummy — use sharp positive-rake tools, high rake angles, generous chip clearance and low cutting speed with air cooling; die-cutting, slitting and waterjet are usually preferred over milling.
Can PVC-P be welded?
Excellent high-frequency (dielectric) and hot-air/hot-wedge weldability due to the polar C–Cl bond; solvent bonding with THF/MEK cements and hot-plate welding also work; avoid overheating, which liberates HCl.
Can PVC-P be formed, bent or molded?
Extruded, calendered, injection or dip-molded at 155–195 °C melt with mold 20–55 °C; keep residence time short and use stainless or hard-chromed, well-vented tooling since degradation releases corrosive HCl.
What surface finishes work on PVC-P?
Accepts embossing, printing with PVC-compatible inks and lacquer topcoats; surfaces should be cleaned of plasticizer bloom before bonding, and plasticizer migration must be checked against adjacent paints, PC/ABS parts and elastomers.

PVC-P HT105 — frequently asked
What is PVC-P HT105 used for?
PVC-P HT105 is typically used for electrical wire & cable insulation/jacketing, flexible tubing and hose, vinyl flooring and film/sheet and inflatable products and gaskets. In short: flexible, RF-weldable PVC; low-cost cable insulation; 300 % elongation.
What is the tensile strength of PVC-P HT105?
PVC-P HT105 has a typical tensile strength of 18 MPa (2.61 ksi) — weaker than 70% of polymer grades. Strength varies by condition: see the 10 listed tempers.
Is PVC-P HT105 easy to machine?
Not especially — machinability is rated fair (40/100, worse than 82% of polymer grades). Machinable but gummy — use sharp positive-rake tools, high rake angles, generous chip clearance and low cutting speed with air cooling; die-cutting, slitting and waterjet are usually preferred over milling.
Can PVC-P HT105 be welded?
Yes — weldability is rated excellent (86/100). Excellent high-frequency (dielectric) and hot-air/hot-wedge weldability due to the polar C–Cl bond; solvent bonding with THF/MEK cements and hot-plate welding also work; avoid overheating, which liberates HCl.
What surface finishes work on PVC-P HT105?
Accepts embossing, printing with PVC-compatible inks and lacquer topcoats; surfaces should be cleaned of plasticizer bloom before bonding, and plasticizer migration must be checked against adjacent paints, PC/ABS parts and elastomers.
Can PVC-P HT105 be formed, bent or molded?
Extruded, calendered, injection or dip-molded at 155–195 °C melt with mold 20–55 °C; keep residence time short and use stainless or hard-chromed, well-vented tooling since degradation releases corrosive HCl.
What is the maximum service temperature of PVC-P HT105?
PVC-P HT105 is rated for continuous use to about 105°C (221 °F), and briefly to 136°C. Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
What is the difference between PVC-P SHA80 and PVC-P CLR?
SHA80 is the default condition — default flexible PVC: wire insulation, hose, profiles and moulded plugs; best all-round property/price balance. CLR: pick for sight-glass tubing, transparent hose and flexible windows where flow visibility is required.
