When the gap to be sealed between two rectangular surfaces having sharp corners or to seal two surfaces with irregular profile, in these cases customized moulded seals are used instead of the conventional extruded compression seals. The advantage of custom moulded seals is that the dimensional accuracy is well maintained especially around sharp corners or joints . Moulded seal’s shape does not deform at any spot in the seal. If its required to have a razor sharp fitting in an assembly, that is where moulded door seals are used.
Elastomers used for manufacturing Moulded door seals:-
- 1) Silicone rubber has chemical resistance , FDA compliance and excellent elongation properties
- 2) FKM has excellent chemical resistance and high temperature resistance
- 3) Natural Rubber is seldom used because of its poor aging properties except in cases where abrasion resistance is required.
- 4) Buna N / Ntrile has good physical properties and excellent resistance to petroleum based fluids
- 5) EPDM has very good weather resistance as well as steam resistance
- 6) Chloroprene has good weather resistance and flame retarding properties
