DURABILITY AND WATER RESISTANCE UNDER EXTREME CONDITIONS
Hydrolysis is a chemical reaction by which polymers are broken down by the action of water. This reaction causes a breakage of molecular chains, loss of molecular weight and a loss of polymer properties, especially toughness.
Hydrolysis is a slow process at room temperature, but can be rapid at high temperatures. This is an irreversible process, since even drying the material will not restore its initial properties.
Some applications require materials with special properties to resist hydrolysis, such as tanks, pipes and ducts where the polymeric material is in contact with hot water, steam or water-glycol mixtures.
PROMYDE HSA HR: PA6 with resistance to HYDROLISIS
NUREL has recently developed PROMYDE® HSA HR a range of special glass fiber reinforced PA6 grades specially designed for parts requiring extreme hydrolysis resistance.
After a comparative test, our PA6 HSA HR grades have been shown to outperform even special PA66 grades with hydrolysis resistance in durability.
NEW HYDROLYSIS RESISTANT PROXYLENE PBT
PROXYLENE HR PBT polymers offer very high resistance of the PBT polymer to prolonged exposure to high temperature water. Contact with water in polyesters, even in the form of atmospheric humidity, causes hydrolytic breakage of the polymer chains and thus weakening of the material, especially at elevated temperatures.
PROXYLENE HR PBT incorporates additives that greatly retard hydrolytic degradation, significantly extending the shelf life of the final product. PROXYLENE HR PBT are non-reinforced PBT grades for injection molding and extrusion.
PROXYLENE B96 P2 G30 HR, after an extreme hydrolysis resistance test (100% RH, 85ºC), and an aging test (3000h, 150ºC), showed a relevant effect in continuous use.
NEW HYDROLYSIS RESISTANT TERYLENE PBT
PROXYLENE HR PBT polymers offer very high resistance of the PBT polymer to prolonged exposure to high temperature water. Contact with water in polyesters, even in the form of atmospheric humidity, causes hydrolytic breakage of the polymer chains and thus weakening of the material, especially at elevated temperatures.
PROXYLENE HR PBT incorpora aditivos que retrasan en gran medida la degradación hidrolítica, prolongando considerablemente la vida útil del producto final. PROXYLENE HR PBT son grados de PBT no reforzados para el moldeo por inyección y la extrusión.
