Elastomers
ELASTOMACH series for PU elastomers
Low pressure for PU elastomers: up to 150 kg/min, up to 150 °C, dynamic head and up to 4 additional components.
Automotive and industrial filters
Reliable sealing starts with correct metering.
End caps, seals and bonding of filter elements.
The process
How polyurethane is used in filters
In air, oil, fuel and cabin filters, polyurethane forms end caps, seals and gaskets that must seal well and withstand use. Metering off-ratio compromises sealing and strength.
Sulpol develops metering machines for expanding, compact and adhesive polyurethane, and automation to suit each customer’s needs.
