PLA forms at 105 to 145 °C, which means it runs on a machine set up for PET with the heaters turned down. The complication is that amorphous PLA softens at 55 °C, and a coffee cup is hotter than that.
A 2.5 metre pipe cannot be extruded on a 2.5 metre line. Winding a profile onto a mandrel makes it possible, and the stiffness comes from the structure rather than the wall.
Polyetherimide moulds at 370 °C, needs four hours of drying at 150 °C, and punishes a long residence time with chain scission. It is a material that rewards a disciplined shop.
Fluorosilicone drops fuel swell from 100 percent to under 20. It also costs three to five times standard silicone and gives up cold flexibility. Here is when that trade is worth making.
HDPE is cheap, tough and chemically resistant, and it is the most awkward polyolefin to thermoform. The window is 20 °C, the sheet sags, and the part keeps shrinking for a day.
A corrugated pipe gets SN8 stiffness from geometry rather than material. Two extruders, a corrugator and a set of moving mould blocks make a wall that is 60 percent air.
Polyphenylsulfone is the material you specify when a part must be clear, sterilisable and survive 1,000 steam cycles. It also moulds at 370 °C, which changes everything about the tool.
RTV cures without heat, tools in a day and is the fastest route to a silicone part. It is also the weakest, most expensive per kilogram and the wrong answer above a thousand pieces.
Acrylic forms at 155 to 190 °C and turns white at every radius if you go in cold. The clarity survives only if the sheet is dry, the mould is hot and the radius is generous.
PE-RT is a polyethylene that holds its pressure rating at 70 °C without being crosslinked. That one property makes it recyclable, weldable and cheaper to make than PEX.
PVC is the only commodity resin that will destroy your machine if you get it wrong. The window is 185 to 205 °C, and the failure mode is hydrochloric acid.
LSR is not rubber moulding with a thinner material. It is a metering process, and one percent of mix ratio error costs you four percent of cure — which you will find in the field, not on the line.
