Description of Output

Outcome/Significance

Refined protocols for preparation of ultra-low protein latex and dry rubber.

Production of latex/dry rubber with technological properties suited for niche medical and engineering applications.

Gamma irradiation for preparation of protein-free latex (US Patent No: 6090328).

Useful for making highly transparent  medical rubber devices, baby products, transparent balloons etc.

An eco-friendly method for the preparation of natural rubber latex carbon black master-batch (US Patent No. 8716366).

Avoids high energy consuming dispersion process of carbon black incorporation in the dry stage, thus saving energy and reducing carbon footprint.

Novel method for preparation of natural rubber latex-silica master-batch.

Better properties for vulcanizates, saves energy and reduces carbon footprint of the product.

Pilot plant scale production of different grades of epoxidised natural rubber with improved silica affinity (Patent No. 21742/2008).

Potential to replace solution SBR in car tyres without compromising performance and thus reducing carbon footprint.

New polymeric filler system for reinforcing natural rubber vulcanizates.

Improves properties of the vulcanizate finding applications across the board in the rubber products manufacturing industry with diverse outcomes. E.g. When used in tyres, it will increase fuel use efficiency.

Identification of a modified coagulant for fast coagulation and maturation of latex.

To make good quality sheet rubber in the shortest possible time.

Technique for making good quality sheet rubber from ammonia preserved latex.

Enabling smallholders and group processing centres to switch between selling preserved latex or sheet rubber made from ammonia preserved latex to capitalise on the market.

A simple, environmental friendly and cost effective method for fast and efficient coagulation of skim latex.

Excellent quality of rubber recovered from skim latex and reducing processing time and drudgery of workers.

Effective coagulation to recover rubber from acid wash serum in sheet making units.

Prevents effluent treatment plants from getting clogged by rubber particles.

Alcohol coagulation and microwave drying methods for quick estimation of DRC of latex.

Convenient for growers, traders and rubber tappers for quick, on-the-spot settlement of payments according to rubber content.

Protocol for low temperature preservation of latex (ammonia free).

Facilitates storage of latex to catch better market price.

The processing and technological properties of latex produced in NE region was studied and found that this was of good quality

Removed an unfounded apprehension that rubber produced from Northeast is inferior and thus prevented growers from exploitation by unscrupulous elements.

Problem of incomplete coagulation of latex during sheet making in NE region due to severe cold during winter season was resolved by modifying the concentration of acid.

Unnecessary wastage of rubber through incomplete coagulation was prevented and thus helped to avoid loss of revenue for growers.

Designed and developed a modified trolley for drying sheet rubber which can save 40 to 55% firewood in the smokehouse (Indian Patent No. 212512).

A user-friendly device for drying of sheet rubber, saves energy, improves quality of sheets and reduces cost of drying.

Designed and developed a cost effective sheet processing machine with less foot-print area.

User-friendly and cost effective machine for the production of good quality sheet rubber at reduced cost.

High-rate methanogenic reactor for treating sheet processing effluents for producing biogas and use of renewable energy for drying sheet rubber in smokehouse.

Reduces carbon footprint of sheet making and saves drying cost.
