Separation of blanks, support of compression moulding.

Separating agents for Extrusion

In numerous polymer processing industries, reliable separation of uncured extrudates is essential for efficient production. Simultaneously, the subsequent vulcanization in the molding process must be supported.

In discontinuous production, semi-finished products typically need to be stored between steps. When dealing with uncured parts, there is a risk of undesired adhesion between the pieces. This challenge is commonly encountered in the production of shoe sole blanks, conveyor belts, profile strips for cold retreading, hoses, and all types of calendered sheets.

It is necessary to use a release agent during the intermediate storage between these steps. The choice of release agent depends significantly on the requirements in the subsequent processing stages. The release agent must not interfere with adhesion and vulcanization during later stages.

silicone-free

PROMOL® SL 5500 is a whitish liquid used in the rubber industry to prevent surface sticking of unvulcanized rubber compounds in the form of sheets, strips, extrudates or blanks. It is used in the dipping unit of batch-off lines or with similar application devices.

The product offers numerous advantages:

  • excellent separation effect for wide range of rubber compounds
  • low consumption rates in comparison to similar products available on the market
  • very uniform release coating due to excellent wetting properties
  • resistant to foam generation
  • sufficient grip for enhanced mill and extruder feeding
  • very high compound compatibility

Release agents for tread blanks for tire retreading

During tire retreading, vulcanized treads are applied to the prepared tire using a cold process. To manufacture these treads, blanks are first extruded, which are then vulcanized in presses. During vulcanization, they also receive their profile. For intermediate storage between extrusion and vulcanization, we have special release agents for unvulcanized tread blanks.

Release Agents for the Hose Industry

During the production of tubes, mandrel lubricants, release agents for the core exteriors, and release agents for the tube exterior are required. Detailed information can be found in our product range for the hose industry.
