Vydyne® R525H Series resins are hydrolysis resistant, 25% glass fiber, reinforced heat stabilized, Nylon 66 resin. Available in natural and black. It is specifically designed to maximize the retention of physical properties when exposed to anti-freeze solutions at elevated temperatures. These products are lubricated for improved machine feed and flow.

Glass reinforced Vydyne resins provide higher heat distortion temperature,resistance to creep, and better dimensional stability when compared with unreinforced Nylon 66. These products have good chemical resistance to a broad range of chemicals including gasoline, hydraulic fluids, and most solvents.

Vydyne R525H Series are heat-stabilized to minimize oxidative degradation of the polymer when exposed to elevated temperatures in service. This product provides improved retention of physical properties under exposure to long-term heat. Also, Vydyne R525H Series resins have excellent knit-line strength and fatigue resistance, which is essential for cycle testing with anti-freeze solutions.

Typical Applications/End Uses: 

Vydyne R525H Series are used for under the hood automotive applications. Their hydrolysis resistant properties make R525H Series resins are excellent candidates for radiator end tank and heater core applications.
