The internal structure can be processed with a two-layer, three-layer, or spiral return water cooling design to assist in roller surface cooling. The rubber layer adopts a two-layer construction: the total thickness of single-side rubber wrapping is 7mm (the bottom rubber is about 5-5.5mm using solid silicone rubber, and the surface rubber layer is 1-1.5mm using nano liquid silicone rubber) Nano liquid silicone rubber rollers mainly performance and advantages A. Mainly produce transparent and 3D products; B. The surface rubber has no seams, indirectly resistant to high temperatures above 300 degrees, and meets environmental protection requirements; C. No seams on the surface; D. The rubber roller surface has no capillary pores, excellent glossiness, mainly producing thinner and transparent films; Nano liquid silicone rubber rollers are widely used in casting machines, pressing machines, laminating machines, etc... Applicable range: PVC, PP, PE, EVA, PEVA, PET, PC, TPU products.
