In industries such as metallurgy, petrochemicals, and high-end electronics, thermal stability is the foundation of operational safety. Standard rubber components often fail when exposed to prolonged heat, leading to brittle fractures or seal degradation. At Unicor Polymer Technologies (UPT), we specialize in high temperature rubber seals for conditions ≥150℃, providing mission-critical solutions where material performance is non-negotiable.
Selecting the right polymer is the first step in surviving extreme temperatures. UPT masters material science across 20+ polymer formulations to ensure your seals remain elastic and effective.
Silicone (VMQ): Our premier choice for wide temperature stability, capable of operating from -60°C to 200°C. It is odor-free, non-toxic, and ideal for medical precision and food processing.
Fluoroelastomer (FKM): Engineered for the most unforgiving conditions, FKM offers exceptional resistance to aggressive chemical media and heat up to 250°C.
Specialized EPDM & PVC Compounds: Custom-compounded for industrial equipment to provide stable leak-proof sealing up to 180°C.
Heat causes materials to expand, making dimensional accuracy vital. Our O-rings and sealing rings are engineered with a dimensional tolerance of up to ±0.05mm, ensuring a perfect fit for delicate electronics or heavy-duty hydraulic systems. For high-pressure environments, our metal wound hoses handle temperatures up to 180°C while withstanding pressures of 100MPa.
We don’t guess—we validate. Spanning approximately 500 square meters, our laboratory is fully equipped with advanced apparatus to test performance under stress. To guarantee our high temperature rubber seals for conditions ≥150℃ meet global standards, we utilize:
High and Low Temperature Alternating Humidity and Heat Test Chambers to simulate real-world thermal cycling.
Ozone Aging Test Chambers to verify long-term environmental durability.
Rigorous mechanical testing for tensile and tear strength to ensure structural integrity at peak heat.
Since 1994, UPT has been a certified high-tech enterprise integrating R&D and manufacturing. Our production facility is IATF 16949, ISO 14001, and ISO 9001 certified, ensuring that every batch delivered to 50+ countries meets the highest quality benchmarks.
Q: How to select the right rubber strip material for ultra-high temperature working conditions (≥150℃)?
A: The selection depends on the media contact and mechanical load. For extreme hygiene and high-end electronics, Silicone (VMQ) is preferred due to its -60°C to 200°C range. For aggressive chemical media or mining applications, FKM or specialized metal wound solutions are recommended for stability up to 180°C-250°C.
Q: What are the key steps of full-process quality control for these rubber products?
A: UPT achieves full-process control from polymer material R&D to final certification. During production, QC engineers perform cross-section checks under 10x magnification every 20 minutes to measure dimensions, tolerances, and geometric errors, ensuring they match design drawings exactly.
Q: Can UPT provide custom high-temperature solutions for complex geometries?
A: Yes. We support One-Stop Rubber Solutions, which include Consultation, Design, and Validation. We offer full-spectrum customizability for special-shaped rubber parts and complex molded components regardless of material or mold complexity.
Q: Are your high-temperature materials compliant with safety standards?
A: Absolutely. Our silicone solutions are Food & Medical Grade compliant (GB 4806.11), and our industrial materials meet ASTM, ISO, and GB standards.
