·Dual-formulation nano-modified food-grade silicone layer with temperature range -60℃~230℃, no sticking or extractable contamination at high temperatures. Guangyu self-developed high-low temperature dual-system silicone formulation, available in general industrial type and LFGB food contact special type, distinguishing from ordinary silicone that only withstands conditions within 150℃. Continuous operation at 210℃ for film hot-pressing, nonwoven thermal bonding, and thermal transfer causes no softening or silicone migration contaminating substrates. When pressing PLA biodegradable films, hot-melt adhesive films, and food packaging films, no adhesive residue remains, and the finished surface shows no white haze or silicone spot defects, perfectly eliminating the common problems of metal roller sticking at high temperatures and scratching soft substrates.
·Patented molecular bonding primer technology ensures the silicone cladding layer achieves no delamination or adhesive failure with the steel core, remaining crack-free at high speed of 80m/min. Departing from the industry's simple grinding and bonding process, Guangyu's proprietary silicone-steel composite bonding patent employs dual treatment of nano-etching on the steel core surface plus specialized silane primer, forming molecular-level bonding between silicone and metal core. Under long-term reciprocating compression and alternating hot-cold cycles on wide-width high-speed production lines, the cladding layer edges show no lifting or localized detachment. Customer comparative tests show 85% longer service life than ordinary bonded silicone rollers, significantly reducing downtime and re-cladding costs.
·Flexible cushioning elastic structure with Shore A20~95 full hardness adjustability delivers uniform pattern depth on uneven soft substrates with zero scratching. Special alloy rollers with high hardness and rigidity easily puncture and scratch thin films, nonwovens, and soft PU synthetic leather. This silicone embossing roller relies on controllable compression resilience characteristics to adaptively conform to substrates with uneven thickness and slight undulations, achieving uniform pattern depth across the entire material width. Low hardness 20~40A suits ultra-thin optical films and baby nonwovens, while high hardness 70~95A suits rigid PVC sheets and thick leather hot-pressing, with one roller compatible with multiple flexible substrate types.
·Ozone-resistant and anti-aging silicone rubber matrix maintains 36 months of continuous outdoor/UV production without hardening or cracking. Ordinary PU rollers experience embrittlement and powdering within 3~6 months under UV and ozone exposure, while ordinary low-cost silicone easily yellows. Guangyu incorporates nano-silica anti-aging filler, resisting UV, ozone, and mild acid/alkali corrosion, suitable for outdoor building decorative film and UV-coated film embossing lines. The rubber surface remains non-hardening and free from fine cracks over long-term use, eliminating frequent roller replacement.
·Seamless integrated vulcanized molding pattern with no splicing seams, smooth transition edges for micro-breathable textures and delicate leather grains. Using integral compression molding high-temperature vulcanization pattern technology, distinguished from segmented silicone sleeve simple processing methods, the full roller length features no seams or raised dividing lines. 0.3mm fine micropores, simulated leather grain, wood grain, and diamond anti-slip patterns are reproduced softly, avoiding the sharp pattern edges common with steel roller engraving that scratch fabrics, significantly enhancing the hand-feel of high-end upholstery and medical hygiene materials.
