Business Description
**Hebei Shuzhi Rubber Products Co., Ltd. - Precision Engineered Sealing & Fluid Transfer Solutions**
### **Core Product Expertise**
As a specialist in high-performance rubber components, we deliver critical solutions for automotive and industrial sectors through five core product lines:
1. **EPDM Automotive Sealing Strips**
Engineered for doors, windows, trunks, and sunroofs, our EPDM seals offer exceptional resistance to UV, ozone, and extreme temperatures (-50° C to +140° C). Features include integrated metal carriers for structural integrity, low compression set (<25%), and customizable surface finishes (smooth/flocked/coated) to reduce friction and noise. Compliant with ISO 4637 and OEM standards like PV 3341.
2. **NBR Foam Sealing Strips**
Designed for oil-rich environments, these closed-cell foam strips serve engine covers, fuel systems, and industrial machinery. With NBR hardness grades from 70A-90A and densities of 150-500 kg/m³ , they provide superior resistance to fuels/solvents (<15% oil swell per ASTM D471), effective vibration damping, and IP67-rated sealing.
3. **EPDM Sponge/Foam Sealing Strips**
Ideal for HVAC, electrical enclosures, and architectural weatherstripping, our microcellular EPDM foam achieves 35-40 dB sound transmission loss (STC) and maintains watertight integrity with 70% compression recovery. Flame-retardant options meet UL94-HB specifications.
4. **Custom Molded Rubber Components**
Utilizing 100-500 ton presses, we manufacture precision O-rings, grommets, vibration mounts, and complex geometries in EPDM, NBR, Silicone, or FKM. Tolerances held within ± 0.1mm (ISO 3302-1) ensure consistent performance in sealing, insulation, and impact absorption applications.
5. **Automotive Water/Coolant Hoses**
Reinforced with 3-4 ply fabric/steel wire, our EPDM hoses withstand burst pressures exceeding 600 kPa and temperatures from -40° C to +150° C. Fully compliant with SAE J20 R6/R7/R9 standards for radiator, heater, and coolant systems in EVs and ICE vehicles.
