Understanding shipping terms (FOB, CIF) and payment methods (30% deposit) is crucial. Factor in lead times (typically 15-45 days) and potential customs duties. Quality control measures should include:
- Third-party inspection services
- Material testing certificates
- Clear specifications for thickness, hardness, and durability
Types of Rubber & Plastics
Rubber Varieties
Natural rubber offers excellent elasticity, while synthetic options like:
- SBR (Styrene-Butadiene Rubber) - cost-effective for tires
- NBR (Nitrile Rubber) - oil-resistant for industrial use
- EPDM - weather-resistant for outdoor applications
Plastic Categories
Common plastic types include:
- PP (Polypropylene) - lightweight and chemical-resistant
- PVC - versatile for pipes and cables
- ABS - impact-resistant for automotive parts
Functions and features of Rubber & Plastics
These materials excel in:
- Durability: Withstand extreme temperatures (-40°C to 120°C)
- Flexibility: Rubber can stretch up to 500% of original size
- Cost-efficiency: Plastic parts often 30-50% cheaper than metal alternatives
Scenarios of Rubber & Plastics
Typical applications include:
- Automotive: Seals, gaskets, dashboards (40% of rubber consumption)
- Construction: PVC pipes, rubber roofing membranes
- Medical: Silicone tubing, disposable syringes
How to Choose Rubber & Plastics
Consider these factors:
- Environmental conditions (UV exposure, chemical contact)
- Required lifespan (temporary vs permanent installations)
- Regulatory compliance (FDA, REACH standards)
