Description
BN Description WPB wiper is a simple design environment with rubber pressure environment. The water scrubbing medium does not protrude from the shoulder of the seal allowing for a cleaner arrangement when the cylinder is retracted. WPB wipers are available in imperial sizes * Do not have Application No has raw materials Nitrile rubber (NBR) + Metal

MATERIALS

Polyurethane is a material that has the elastic properties of rubber. The proportion in its composition (diisocyanate, polyol, chain extender) is determined by its properties. This material is characterised by a strong mechanical resistance, good wear resistance, high elastic modulus, good flexibility and a very good ozone and oxidation resistance.

Chemical resistance	Pure aliphatic hydrocarbons (propane, butane) Mineral oils and greases Silicone oils and greases Water up to +50°C
Compatibility issue	Ketones, esters, ethers, alcohols and glycols Hot water, steam, alkalis, amines and acids
Temperature range	-30°C/+90°C -30°C / +110°C with our PUHT (short term peak at 150°C)

NBR

Nitrile rubber (NBR) is the general term for acrylonitrile-butadiene copolymer. The ACN content can vary between 18% and 50%. While the acrylonitrile content is important, the resistance to oil and fuel is more so. Conversely, the elasticity and compression set are not as good. The NBR has good mechanical properties and good wear resistance. However, its resistance to atmospheric agents and the ozone is relatively low.

Chemical resistance	Aliphatic hydrocarbons (propane, butane, petroleum, diesel fuel) Mineral oils and greases Fire-resistant fluids (HFA, HFB and HFC) Diluted acids, low-temperature alkaline and saline solutions Water (up to +100°C max)
Compatibility issue	Fuels with high aromatic content Aromatic hydrocarbons (benzene) Chlorinated hydrocarbons (trichlorethylene) Polar solvents (ketone, acetone, acetic acid, ethylene-ester) Strong acids Glycol-based brake fluids Atmospheric and ozone agents
Temperature range	-25°C/+100°C
