Polyurethanes have a much wider hardness range from 5 Shore A up to 85 Shore D, whereas the useful hardness range for epoxies would be from 40D to 90D. Urethanes tend to be less brittle and have higher tensile elongation than other materials with similar hardness.
Polyurethanes also posses “elastomeric memory” which means that they can withstand considerable deflection (in tension or compression) without permanent deformation. The abrasion resistance of Urethanes is far superior to Epoxies.
Epoxy advantages are physical strength, high temperature resistance and excellent adhesion to most substrates. Urethane advantages are low temperature performance, low exotherm and faster cure speeds
Compared to other adhesive technology, hot melt adhesive have many advantage in the industry application espacially on speed curing and cost effectiveness .
Yes – using different density and specifications, boards are considered as the most efficient and fast solution to design and style prototypes/models,for making master mould & to produce moulds & parts under highly Temperature/pressure with high dimensional stability.
Our customer should provide tous all necssary details(extruder,amount of filler, nature ofstabiliser and other parameters ..)to work on cost saving formula.
