Frequently Asked Questions (FAQ)
What is the main difference between this TPE and traditional rubber?
The primary difference lies in processability. This TPE is a thermoplastic, meaning it melts when heated and solidifies when cooled, allowing it to be processed quickly by injection molding or extrusion. Traditional rubbers are thermosets requiring a slower vulcanization process. TPEs are also recyclable from production scrap.For what kinds of products is a 40 Shore A hardness most suitable?
A 40 Shore A hardness is ideal for applications requiring a soft, flexible, and comfortable feel. Common uses include soft grips for tools and appliances, squeezable seals and gaskets, flexible tubing, protective bumpers, and consumer product components where a gentle touch is desired.Can this TPE SO 2040A be colored?
Yes, it can be compounded with a wide range of color masterbatches to achieve virtually any color. Standard colors may be available, and custom color matching is typically offered upon request to meet specific design needs.Does it adhere well to other plastics during overmolding?
Yes, this grade is formulated to bond effectively with several common thermoplastics, such as polypropylene (PP) and polyethylene (PE). For optimal adhesion, substrate selection and surface preparation should be evaluated during the design phase.What are the recommended storage conditions for this material?
It should be stored in a cool, dry place away from direct sunlight and moisture in its original packaging. Proper storage prevents moisture absorption, which could affect processing and final part quality.Is this material suitable for food contact or medical applications?
The standard SO 2040A grade is a general-purpose material. For applications requiring food contact compliance or medical certification, specific formulations with relevant approvals are needed. Please inquire about specialized grades available upon request.What injection molding machine settings are recommended?
General guidelines include a melt temperature range of 160-200°C and moderate injection speeds. However, optimal settings depend on the part geometry and mold design. We provide processing guidelines with our technical data sheet.How does the cost compare to silicone rubber or other elastomers?
TPE often offers a favorable cost-in-use compared to silicones due to faster processing cycles, lower energy consumption, and material recyclability. It provides a competitive balance of performance and economics for many applications.
