Designed and developed conducting polymer blends, based on PANI, a conducting material supplied by DRDO lab, Jodhpur and using conducting carbon and blending it with different polymers ABD rubbers.

Designed and developed Bone cement is used to fill the gap between bone and prosthesis. Bone cement has been prepared on laboratory scale and physico-mechanical properties were found to be conforming to the international standards.

Development of Dental Cement. Polycarboxylate resin modified glass ionomer based dental cement used for filling dental cavities, fixation of crown, bridges and also as lusting agent has been successfully developed as per international standards.

Effectually provided expert supported to a building materials manufacturer, and successfully completed the low temperature wood/plastic composites which are suitable for extrusion molding at room temperature.

Developed CAPD system with dialysate solution and completed blood bag composition having physico-mechanical as well as hematological properties conforming to ISO 3826.

Disposable vaginal speculum has been developed for gynecological applications. These can replace metallic speculum, which needs to be sterilized for long periods and pose risks of disease transmission if improperly sterilized.

Technically consulted formulation and processing of product developments, such as anti-static PE film apply in wafer spacer, the toughness of nylon composites apply in sole, wear-resistant nylon tube apply in brake cables, a long-lasting anti-fog effect PP packing film, etc.

Identified and solved varied composites failure problems (e.g. recycle materials, selecting alternative materials) by using separation and composition analysis techniques. Extensive experienced in functional polymer-based materials and composites, including PE, PP, PET, PBT, PVA, PMMA, PC, PS, PA/Nylon, ABS, PPO, PVC, TPE, TPU, EVA, NR, NBR, SBR, EPDM, phenolic resin, glass/carbon reinforced composites, nanocomposites, recycled materials etc.

Developed a technology for the manufacture of low cost disposable healthcare products viz. diapers and sanitary napkins have been developed.

Developed Jute composites by replacing polyester and polystyrene with natural Euphorbia latex coagulum. Water absorption properties of polyester coagulum composites are better than polystyrene coagulum composites. This composite can be successfully used as wood substitute.

Developed gamma resistant PVC/PU blends, PS/SBS, PP/EPDM, PP/SEBS, PVC/ABS and PVC/NBR blends have been developed for abrasion resistant low cost lip seal and Booting for nuclear plant conforming to International specifications.

Developed ecofriendly ways for utilization of plastic waste in the following areas - Process Engineered Fuels (PEFs) from plastic wastes, Road Construction and Value Added Products from plastic wastes.
