What kind of plastic is polyurethane plastic?
Polyurethane (PUR and PU) is a polymer composed of a chain of organic units joined by carbamate (urethane) links. While most polyurethanes are thermosetting polymers that do not melt when heated, thermoplastic polyurethanes are also available. Polyurethanes plastic commonly used in the manufacture of flexible, high-resilience foam seating; rigid foam insulation panels; microcellular foam seals and gasket - in.kompass.com/a/bottles-plastic-for-the-pharmaceutical-and-cosmetic-industry/2071009/
Example of a catalyst?
patassium permagenate is a catalyst for hydrogen peroxide breaking it inot water and oxygen
What is the difference between a polyurethane PU coating and a thermoplastic polyurethane TPU coating?
A thermoset is a material that cures or sets into a given shape, generally through the application of heat. A cured, thermoset material will not remelt or otherwise regain the processibility it had before being cured. Curing changes the material forever. A thermoplastic material softens (becomes pliable and plastic) when heated, but it does not cure or set. It can be reheated to be reformed.
What are the types of polymers?
Polyethylene Polypropylene Polystyrene Poly(vinyl chloride) - (PVC) Polytetrafluoroethylene - (Teflon) Poly(methyl methacrylate) - (Lucite, Plexiglas) Polyacrylonitrile - (Acrilan, Orlon, Creslan) Poly(vinyl acetate) - (PVA) Natural rubber Polychlorprene - (neoprene rubber) Styrene butadiene rubber - (SBR) Polyamides - (nylon) Polyesters - (Dacron, Mylar, Fortrel) Polyesters - (Glyptal resin) Polyesters - (Casting resin) Phenol-formaldehyde - (Bakelite) Cellulose acetate - (cellulose is a polymer of glucose) Silicones Polyurethanes
What is BOD incubator?
B.O.D. Incubator is available in two model Standard and GMP model. Its construction is in Double walled, where gap between the two walls filled with high quality called Polyurethanes Foam (PUF). The special range of B.O.D. Incubator are designed & fabricated to match various I.S. standards and to meet requirement of different bio chemical oxygen demand test equipment in various fields like medical, vaccines, agricultural, industrial, research laboratories, culture of bacteria, microorganism, seed germination
