Latex engineered to your process

Four products. One standard of quality

Each product is manufactured to consistent specification, tested in our in-house NIR laboratory, and shipped with full FSC™ Chain of Custody documentation.

• HA Latex Concentrate — High Ammonia
  High Ammonia latex concentrate with ≥60% Dry Rubber Content (DRC). Preserved with ammonia (≥0.60%) for long-distance shipping stability. The most widely used grade globally — suitable for gloves, condoms, catheters, adhesives, and latex foam. Mechanical Stability Time (MST) ≥650 seconds.
• LA TZ Latex Concentrate — Low Ammonia
  Low Ammonia TZ concentrate with the same ≥60% DRC as our HA grade. Ammonia content ≤0.29% — ideal for sensitive applications where residual ammonia is a concern. Used in thin-film medical products, sensitive adhesives, and applications with strict chemical tolerances. MST ≥650 seconds.
• Block Rubber — STR 20 / RSS
  Technically specified ribbed smoked sheet and standard Thai rubber (STR 20). Plasticity Retention Index (PRI) ≥40% — a key indicator of heat-ageing resistance. Wallace Plasticity ≥30. Used in tyres, industrial rubber goods, and general manufacturing applications requiring consistent physical properties.
• NIR Quality-Control Laboratory Testing
  Tat Win is the only TLC (Total Latex Concentrate) manufacturer in the world with a dedicated Near-Infrared (NIR) spectroscopy quality-control capability. NIR testing provides rapid, non-destructive verification of DRC, TSC, and alkalinity on every batch before release — eliminating the wait time of wet-chemistry methods for routine QC checks. Wet chemistry remains the reference standard; NIR provides a real-time verification layer.
