Today's designers are confronted with a bewildering choice of grades of plastics and methods of processing. With such variety, every choice involves a compromise.
At HIL Polymers India Pvt Ltd, we understand the effects processing has on the typical properties of high performance fluoropolymers and engineering plastics.
Our experience and technical knowledge allows us to best align an engineered material with a customer's requirements.
HIL Polymers India Pvt Ltd's engineers can provide material specific technical data including:
» Tensile Strength & Elongation
» Specific Gravity
» Thermal Expansion
» Weep & Memory
» Wear and Friction
Design & Engineering Services include:
Design Assistance We can help take your concept to a production ready design using 2D & 3D CAD tools. APT engineers work with both AutoCAD® and SolidWorks® native formats, and we can import many file types including DXF, IGS, STEP, IPT, PAR & others.
For complex projects involving more extensive development, we are happy to work with you under an R&D purchase order. For the fastest response to your RFQs, please email your dimensioned 2D drawings as PDF or DWG files. Thank you!
