Rubber Testing Services
Rubber and Plastics, a section of Analytical Science Division of J.K.LABORATORY, is engaged in testing and research in the field of polymers.
Polymers comprises broad spectrum of materials including Plastics, Rubber, Resins and Fibers. They find application in various sectors of life from domestic to strategic applications. Testing and characterization of polymers are important to assess the quality and performance of materials and products made of them. We offer broad range of testing and research services to customers from various sectors.
Our Customers Include
- Product/Raw material manufacturing industries that want to test their Product or Raw material for certification, research, identification of the nature or composition of competitors/market-picked products.
- Govt. agencies/Independent agencies who want to ensure the quality of incoming materials.
- Research organizations that want to characterize materials for research.
Services We Offer
- Consulting services for the diagnosis and technical evaluation of processes and products, solution of problems in situ.
- Characterization of polymeric materials.
- Research & development projects.
- Contractual projects for troubleshooting, problem solving and technology development.
- Development of new testing facilities/methods as per customer requirements.
- Quality control testing and certification.
- Site Inspection and Certification.
- Third party quality checks.
- Setting up of the new laboratories and development and implementation of quality systems.
- Inspection and quality checks of polymeric products for exports, Government supply and vendor development
