TPV roller

Problem-Solution Intro

Is Your Sealing Failing in the “Hot Zones”? In the developing and drying stages of a PCB horizontal production line, temperatures often fluctuate or remain consistently high (above 60°C). Standard PVC rollers lose their “memory” and elasticity in these conditions, leading to seal gaps and chemical steam leakage. The SN:6-5 TPV Roller is engineered to bridge the gap between low-cost rubber and expensive fluoropolymers. It maintains a perfect, flexible seal even when your equipment is running at a sustained 110°C.

The “Why This Material” Section

TPV: The Best of Both Worlds Thermoplastic Vulcanizate (TPV) offers the high-performance sealing of EPDM with the processing precision of a plastic. For the SN:6-5, this means:

• Superior Compression Set:Even after thousands of hours under pressure, the roller won’t develop “flat spots,” ensuring the 15mm radial runout remains constant.
• Thermal Expansion Control:TPV has a lower thermal expansion coefficient than standard PVC, meaning your machine’s tolerances won’t shift as the line heats up.
• UV & Ozone Resistance:Ideal for modules exposed to UV curing or harsh industrial atmospheres without cracking.

Customization Capability

Tailored for Equipment Maintenance Leads We don’t believe in “one size fits all” for high-heat modules. QXY provides:

• Custom Hardness (Shore A 55-65):Need a softer touch for ultra-thin substrates? We tune the TPV density to your spec.
• Exotic Axis Options:High heat + chemicals = rapid corrosion. We offer Titanium (Grade 2) or Carbon Fiber axes to ensure the core lasts as long as the TPV shell.
• Precision Surface Grinding:Available in ultra-smooth or micro-matte finishes to control “tackiness” in hot environments.

Main Application Scenarios

Sealing integrity often fails when temperatures climb, and the SN:6-5 is built specifically for these “hot zones.” In PCB Drying and Developing modules, where 60°C+ is the norm, standard PVC rollers tend to lose their “memory” and warp. This TPV model thrives in those conditions, maintaining a tight, elastic seal up to 110°C.

It is a critical component for High-temp Rinsing sections and UV Curing lines where ozone and heat typically cause generic rubbers to crack. By resisting “flat spots” even after long periods of compression, it ensures your panels transition between tanks without steam leakage or chemical carry-over. If your maintenance team is tired of swapping out heat-damaged seals every few months, the SN:6-5 is the direct upgrade.
