CF12/CF15/CF19/CF27
CF12/CF15/CF19/CF27
- Film thickness distribution directly from the melt provides high strength and prevents shape reversion at elevated temperatures.
- PP exhibits higher strength than PVC due to greater film thickness, despite having the same geometry and weight.
- Fully automated welding is cost-effective and offers greater strength compared to mechanical pressing.
- No use of adhesives or solvents, reducing environmental pollution.
- PP can be used continuously up to 75°C, while PVC is suitable up to 55°C.
- Manufactured from PP/PVC granulate with high UV protection additives.
- On-site fabrication is possible to reduce transport costs, thanks to automatic welders.
- Extensive global installation with technical support for various applications.
- Effective surface area and channel width vary by model: CF12 (240 m²/m³, 2x12 mm), CF15 (190 m²/m³, 2x15 mm), CF19 (150 m²/m³, 2x19 mm), CF27 (125 m²/m³, 2x27 mm).
- Materials used are UV-stabilized PP and PVC.
- Standard dimensions are 2400 x 300 x H: 600/300/150 mm.
- Void percentage is greater than 97%.
- Weight of new plastic ranges from 20-60 kg/m³, with density for PP at 0.95-1.1 g/cm³ and PVC at 1.4-1.6 g/cm³.
- Foil thickness is less than 1.5 mm before forming.
- Operational temperature ranges: PP from -20 to 75°C, PVC from 0 to 55°C, with further specifications available on request.
- Hewitech provides a computer program for further technical details available at www.hewitech.com.
- Production conforms to REACH regulations, ensuring raw materials are listed and approved.
- Polypropylene is noted for its excellent chemical and UV resistance and is environmentally friendly.
- Drinking water certification is available upon request.

fiewTtecfi I N N OVATI 0 N IN PLASTIC CF12, CF15, CF19 + CF27 Over 20 years ago Hewitech developed the first welded film cooling fills in PP - shaped, extruded films in a single step from the melt. Films with a thickness distribution lead to high-strength blocks - with sharply reduced material input! Deformation of flat films is history. Today Hewitech manufactures not only film cooling fills of PP but also of welded PVC - free of adhesives and solvents. Features and advantages: - film thickness distribution directly from the melt - giving extremely high strengths and no possibility of reverting to original shape at elevated temperatures - with same geometry and weight: PP exhibits higher strength than PVC because of greater film thickness - fully automated welding - very inexpensive and substantially greater strength than 'mechanical pressing' - Hewitech dispenses with adhesives and solvents which pollute the environment - PP up to 75°C continuous use temperature; PVC up to 55°C - produced from PP/PVC granulate with high percentage of UV protection additives - on-site fabrication to reduce transport costs possible thanks to automatic welders - hundreds of thousands of cubic metres installed worldwide - technical support for different applications
