Product Description: Premium S.T.R. 5L (Low Impurity, Light Color)
Standard Thai Rubber 5 Light (S.T.R. 5L) is a premium technical specification grade, renowned for its excellent purity and highly desirable light color. Produced exclusively from fresh, clean field latex, S.T.R. 5L is the ideal choice for manufacturers whose final products require both high mechanical performance and a clean, consistent aesthetic. It strikes a perfect balance between high quality and broad applicability.

Plasticity Retention Index (PRI) | 60 min. |
Lovibond Color (Units, Max) | 6 |
✨ Premium Grade Advantages
Low Impurity (Dirt $\leq 0.05\%$): Manufactured to meet the demanding S.T.R. 5 standard, the controlled low dirt content minimizes defects, making it suitable for applications that require a smooth, flawless finish and reliable performance.
Excellent Light Color: The "L" for Light designation confirms that the rubber meets a low Lovibond color maximum (6 units). This makes it essential for producing goods that are light-colored or require high visual quality and color consistency after compounding.
High Physical Properties: Processed from quality latex, our S.T.R. 5L exhibits high elasticity, tensile strength, and good processing characteristics (high PRI), ensuring durability and resilience in the final product.
🎯 Recommended Applications
S.T.R. 5L is highly valued across several industries, particularly where appearance and purity are critical:
Footwear Manufacturing: Premium light-colored soles and components.
Medical Supplies: Non-staining and light-colored components (e.g., examination gloves, closures).
Molded Goods: High-quality rubber products where internal and external cleanliness is vital.
Adhesives and Tapes: Applications benefiting from the rubber's high purity and low color.
📦 Packaging and Logistics
Weight: Standard $33.33 \text{ kg}$ compressed bales (or tailored to client requirements).
Packaging: Standard polyethylene wrapped, meeting international export specifications.
