Polyurethane Molding & Urethane Casting | Novathane Co | Nova, OH

Excellent wear resistance, Novathane Polyurethane is a cast elastomer which has the versatility to be molded in a wide range of techniques and properties. Novathane is a preferred supplier at a Design-2-Part Show. Polyurethane ALLOWS FOR IMPROVED PRODUCT PERFORMANCES IN A WIDE RANGE OF APPLICATIONS. For applications of polyurethane that involve water the parts can be cast using polyether-based resins. However, polyester-based resins are more practical for resisting damage from strong abrasions, like cuts and tears. HARD AS BONE OR SOFT AS RUBBER A product created with Novathane Polyurethane has a unique advantage. The polyurethane elastomers can be altered for a hardness level ranging from 10-15 Shore A (durometer). This can be compared to the softness of a gum eraser. This level can also be changed to over 80 Shore D (durometer), exceeding the hardness of a golf ball. Novathane Polyurethane can be altered to a variety of hardness levels - even more than conventional rubbers. View our interactive hardness graphic to see how materials and uses correspond. RESISTANT TO ABRASION In many applications of polyurethane elastomers, good resistance to abrasion, and low coefficient of friction are essential characteristics. The lowest coefficients of frictions are achieved with high hardness formulations. Additives can also increase the COF to achieve a comparable UHMW solution adding toughness to your application. In comparison to rubber, plastics, and even some metals, Novathane Polyurethane elastomers have a definite wear advantage. HIGHLY RESISTANT TO IMPACT Conventional plastic materials can become brittle and weak over time. Unlike plastic, polyurethanes remains elastic and resist fracture. This amount of toughness makes polyurethanes ideal for parts that have to hold against high impact or repeated impingement. WIDE RESILIENCE RANGE Unlike rubbers, high hardness polyurethanes can be just as resilient as softer materials. In shock absorbing applications, low rebound compounds are usually used in the range of 10-40%. In high frequency vibrations or where quick recovery is needed, compounds of 40-65% resilience are used. In general, toughness is enhanced by resilience. FLEXIBLE AT WIDE RANGE TEMPERATURES Polyurethanes can be used in all sorts of temperatures. When exposed to freezing temperatures they remain quite flexible, are resistant to thermal shock, and can withstand sudden temperature drops without cracking. If higher operational temperatures are required. Novathane Polyurethane can go under continuous use at 90C (194F) OR special high temperature formulations can be used up to 350F. ELECTRICAL PROPERTIES Novathane potting polyurethanes are excellent insulators. They are used extensively in potting and encapsulating applications, as well as other areas where electrical isolation is vital. WIDE RESISTANCE TO OIL, GREASE, AND CHEMICALS - Novathane Polyurethanes resist a broad range of liquids. Novathane 228 Twp. Rd. 931 Nova, OH 44859 Ashland County http://www.novathanedirect.com
