Polyurethane foam is a resilient open-celled material which offers superior cushioning and protection properties. discoloration on exposure to UV radiation is not an issue, whereas aliphatic isocyantes are preferred for applications in the coating and adhesive industries. Polyurethane products are stronger, tougher, and more durable than those made with conventional elastomers and plastics. The first Polyurethanes were manufactured as millable gums and so could be processed on normal rubber manufacturing equipment. We manufacture cast polyurethane products from sample parts, dimensional drawings or just give us a call to discuss your application. However, polyethers are usually more expensive than polyesters. and TDI are often prefered for coatings, sealants and adhesives. Polyurethane routinely outperforms plastic, rubber and steel in its overall ability to resist harsh environmental factors such as abrasion, heat, solvents, oil and acid. They are used in a very broad range of products. The range and depth of properties that are fulfilled by V-THane polyurethane is almost too good to be true.

For example, polyester-based urethane elastomers have better A range of common recycled plastics are selected. Poly THF® (BASF). While thermoset polyurethanes can provide similar performance and can meet individual property needs, the full combination of properties available in an ABS material cannot be attained in a polyurethane system. is usually supplied as a mixture of two isomers: 2,4-TDI and 2,6-TDI (see table below). Cast Polyurethane's most unique characteristic is its extremely broad hardness range. Some formations also have good flame resistance. hard or flexible and soft. Temperature, cost, mechanical properties, electrical insulation, FDA, chemical resistance? The elastomers have excellent abrasion resistance but high hysteresis; the associated heat build-up has limited their use in applications such as tires. Properties / Applications: The product was designed specifically for the coating of plastic substrates. Due Because urethane is available in a very broad hardness range (eraser-soft to bowling-ball-hard), it allows the engineer to replace rubber, plastic and metal with the ultimate in abrasion The soft segments comprise the larger portion of the elastomer and, therefore, determine the The structure determines whether a polymer is polar or non-polar and this in turn decided the electrical properties of the polymer. TPU provides a large number of physical and chemical property combinations for the most demanding applications such as automotive, wires and cables, breathable films for leisure, sports and textile coatings, weatherable, non-yellowing films etc. to the low polarity and high flexibility, PPG and PTMO polyols are liquid at room temperature, whereas most A range of common recycled plastics with similar mechanical properties to polyurethane are selected.
