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
