PROEXPORT / INDUSTRIAL ROLLERS
Silicone-Covered Industrial Rollers | PROEXPORT
PROEXPORT silicone-covered rollers provide outstanding thermal stability from -60°C up to +250°C (with short peaks to +300°C), exceptional anti-adhesive (non-stick) surface properties, and high resistance to ozone, corona discharge, and weathering. They are widely utilized in plastic extrusion, film laminating, hot-melt adhesive application, and food packaging.

LINE PROBLEM SOLVING (PWE)
Precision that Eliminates Line Downtime and Web Defects
At PROEXPORT, we do not simply supply coatings — we solve specific engineering challenges for plant technologists and maintenance leaders.
PRODUCTION CHALLENGE
Line Issue
Hot polymers and pressure-sensitive adhesives sticking to roller surfaces, causing web tears and thermal degradation.
PROEXPORT SOLUTION
Engineering Solution
Specially compounded heat-stabilized crosslinked silicone elastomer with chemically vulcanized core adhesion.
PLANT ROI RESULT
Measurable Effect
Completely non-stick web release, elimination of line jamming, and consistent thermal conductivity across the web width.
SELECTION & QUALITY CONTROL
Pre-Production Specification & Quality Inspection
Every project — new fabrication or reconditioning — is executed according to strictly defined inspection points:
- Thermal cycle stability inspection up to max specified process temperature.
- Shore A hardness and wall thickness concentricity measurement.
- Cleanliness inspection for optical film and food-grade packaging applications.
- Dimensional verification of bearing journals and mounting fits.
Technical Acceptance Standards
| Inspection Dimension | Technical Significance |
|---|---|
| Geometry & Tolerances | Diameter calibration, radial/axial runout, and concentricity of bearing journals. |
| Coating Structure | Durometer Shore/HV verification, nominal thickness, and zero-porosity bonding. |
| Dynamic Balancing | Residual unbalance compensation in ISO 1940 Grade G 2.5 or G 6.3. |
FREQUENTLY ASKED QUESTIONS (FAQ)
Frequently Asked Questions (FAQ)
What is the maximum operating temperature for silicone rollers?
Standard industrial grades operate continuously up to +200°C, while high-temperature formulations withstand up to +250°C continuous and +300°C intermittent peaks.
Can silicone rollers be grooved?
Yes. We offer precision longitudinal, circumferential, and spiral grooving on silicone rollers to facilitate air evacuation in web guiding.
