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.
Technical parts
Hardness, abrasion resistance and elasticity under control.
Wheels, rollers, bushings, seals and technical parts.
The process
How polyurethane is used in elastomers
Polyurethane elastomers combine hardness, abrasion resistance and elasticity. They are used in industrial wheels, roller coating, mining, oil and gas, agricultural equipment, transport and technical parts that replace rubber or metal.
The systems usually run heated and with a critical mix ratio. The ELASTOMACH series was developed for these requirements: up to 150 kg/min, tanks up to 1,000 L, temperatures up to 150 °C, automatic degassing and a dynamic mixing head.
Steps
Typical process flow
- 01 Conditioning Prepolymer and curative heated.
- 02 Degassing Vacuum to remove bubbles.
- 03 Metering Critical ratio, precision pumps.
- 04 Casting Heated mould or rotational casting.
- 05 Post-cure Final properties.
Reference flow. Each project defines the steps included and each supplier’s responsibilities.
