Odorless Latex Coagulant

Technology Overview

Rubber growers usually engage in the basic processing of their rubber latex to produce rubber cup lumps which are then supplied to rubber products manufacturers for converting into products such as block rubbers. One of the problems usually faced by the manufacturers is the microbial contamination in the rubber cup lumps, which causes a digestion of protein, carbohydrate and fat contained in the latex, resulting in a malodor in the rubber cup lumps as well as finished products.

An innovative latex coagulant has been developed for the production of odorless rubber cup lumps. In addition to effective coagulation, this coagulant offers anti-microbial property and protein structure modification, making it more resistant to microbial digestion and safer to workers and the environment. The coagulant can completely eliminate the malodor problem in rubber throughout the supply chain.

The technology owner is seeking private or public organisations keen to license this technology for manufacturing.

Technology Features, Specifications and Advantages

This technology encompasses the chemicals formulation and process.

Key technical specifications include:

  • Eliminate malodor problem in the production of rubber products and improve the quality of rubber processing wastewater.
  • Reduce the cost of malodor treatment in the rubber processing factory.
  • Reduce the incubating time of cup lump by 2/3 (from 30 days down to 20 days), thus easing cash flow and saving storage space.
  • Reduce the cost of hydroxylamine neutral sulphate (HNS) in the production of CV rubber by 6 USD or 8 SGD/ton.

Potential Applications

This technology is suitable for rubber growers and contract farmers that produce rubber cup lumps as well as manufacturers of rubber products, such as block rubbers.

Customer Benefits

It is easy to use and can be applied to existing processes performed by growers and manufacturers with minimal modification. The coagulant can completely eliminate malodor problem in rubber products – from cup lump to block rubber and finished products – throughout the supply chain. It is also safe for workers and the environment.
