Custom extruded profiles from Santoprene thermoplastic vulcanizates (TPVs)
We specialize in the manufacture of intricately shaped plastic profiles and in the extrusion of difficult-to-run elastomers, such as Santoprene™, nylon and glass-filled abs.
Santoprene thermoplastic vulcanizates (TPVs) are high-performance thermoplastic elastomers that combine EPDM rubber and polypropylene. Developed originally by Monsanto Company in 1977, they are now owned by ExxonMobil. They can be cost effectively extruded into single and complex profiles.
Santoprene TPVs are distinguished by the desirable characteristics of vulcanized rubber, such as flexibility and low compression set, and the processing ease of thermoplastics. They possess the same levels of manufacturing flexibility and consistent durability that are commonly found with natural rubber compounds. Because of their excellent performance in both extreme hot and cold environments, longer service life, ease of processing, design flexibility and lower system costs, Santoprene TPVs are often chosen as alternatives to rubber for many applications. They can also be recycled.
In general, Santoprene TPVs offer customers:
● Reduced parts weight and costs vs. thermoset rubber
● Reliable parts performance
● Improved manufacturing efficiencies vs. thermoset rubber compounds
Properties and Benefits include: good melt strength, low die swell, good abrasion resistance, a range of hardness grades (35 Shore A to 60 Shore D), good compression set at room temperature, broad operating temperatures from -45°C (-50°F) to 135°C (275°F) with no cracking or tackiness, plus environmental aging resistance, electrical properties, and liquid resistance that are comparable to EPDM, excellent UV resistance, excellent fatigue resistance, resistance to microbial attack, minimal moisture absorption, low specific gravity (0.91 to 0.97), colorable
Applications. Santoprene TPVs have found use in a variety of industrial and consumer markets, including automotive, household appliances, electrical, construction and healthcare, to name a few.
In the consumer area, they are found in insulation material for household appliances, pump gaskets, hose connectors, weather stripping for windows and doors and closure seals on ovens and refrigerators. A number of sporting goods also utilize the plastic, such as grips on baseball bats, insulated handle bar covers for bicycles, skin diving equipment, wet suits, ski pole handles, and the grips on tennis racquets.
Among industrial applications, Santoprene TPVs are utilized on all sorts of tool grips, as well as caster wheels, textile industrial rollers on carding and spinning equipment, and machinery gaskets. Around the office, they may show up in the cushion on the bottom of computer monitors, vibration isolators that slide under speaker phones, and printer rollers. In the automotive industry, the lighter weight of Santoprene TPVs contributes to improved efficiency and reduced costs. The plastic is used in various types of boots, the lining in air ducts, covers for cables under the hood, windshield spacers, and air bag doors
