U-Cup Description

U-Cup Description. U-cups are a lip seal, named for the cross-section’s distinctive “U” shape. i.e. resistance to wear and extrusion gap, resistance to high and low temperature, etc. Listed below are general guidelines and design elements to consider during the selection process. *A = 70 Durometer Nitrile, Fluorocarbon, Ethylene

Rubber Material Reference, Neoprene, EPDM, Buna-N

Material Reference. The chart below is intended to help in the material selection stage of designing rubber parts / products. Rubber compounding is a very broad and technical field, since basic rubbers or elastomers are mixed with various chemicals and ingredients (and even with each other) to obtain desired physical properties.

Vacuum Cup and Suction Cup Material Selection Guide

A vacuum cup needs to flex yet have good elasticity, memory, wear resistance, heat and tear resistance, etc. Every cup type requires the right blend of ingredients to achieve this. Thus a Vacuum Cup is only as good as its specific recipe or mixture of elastomeric compounds.

Orings Viton Vs Hnbr? - Airguns & Guns Forum

Buna-nitrile is generally better in terms of abrasion resistance compared to Viton. The advantage that Viton has in the world of airgunning is it is not permeable to CO2 like Buna-Nwhich of course is not a factor in the two applications you cited. polyurethane is a very tough and wear resistant "rubber" with the only downside being the
