New Alternative Preservative for Extending Shelf Life of Fresh Natural Rubber Latex for Rubber Sheet Production
BeTHEPS is a preservative that can increase the quality of rubber, reduce environmental pollution
and create a good quality of life for rubber farmers.

   • If without any proper preservation, spontaneous coagulation and spoilage of fresh natural rubber latex usually occurs in 6-8 hours.
   • Preservatives are required to extend shelf life of fresh natural rubber latex.
   • Ammonia and sodium sulfite are widely used as commercial preservatives.
   • Ammonia creates toxic fume, endangering workers’ health and causing environmental pollution.
   • Sodium sulfite leaves air pockets in dry rubber sheets, resulting in lowering the rubber sheet quality.

   • Easy to mix with latex in liquid form
   • Reduce the risk of latex coagulation and spoilage
   • Extend the shelf life of latex by up to 1-3 days
