For professionals in the chemical and manufacturing sectors, sourcing high-quality raw materials is fundamental to product success. P-Toluenesulfonyl Semicarbazide (PTSS), also known as Blowing Agent RA, is a critical component for many polymer foaming applications. This guide is designed for purchasing managers and chemical engineers seeking to buy PTSS, focusing on key considerations when selecting a supplier and product.

P-Toluenesulfonyl Semicarbazide (CAS 10396-10-8) is a chemical blowing agent valued for its high decomposition temperature, typically between 224-235°C. This characteristic makes it ideal for foaming polymers processed at elevated temperatures, such as certain types of PVC, polyolefins (HDPE, PP), polycarbonates, and nylon. The controlled release of nitrogen gas upon decomposition creates a fine, uniform cellular structure, imparting desirable properties like reduced weight, improved insulation, and enhanced cushioning.

When evaluating P-Toluenesulfonyl Semicarbazide for purchase, several factors are paramount:

  • Purity: High purity is essential for consistent performance. Look for suppliers offering PTSS with a purity of 98% or higher. Impurities can affect decomposition temperature, gas yield, and the final quality of the foamed product. We, as a dedicated manufacturer, ensure our PTSS meets stringent purity standards.
  • Decomposition Characteristics: Understand the specific decomposition temperature range and gas yield (typically 140-150 ml/g for PTSS). These parameters directly influence the foaming process and the resulting foam structure.
  • Physical Form and Particle Size: PTSS is typically supplied as a white powder. Fine and consistent particle size is important for good dispersibility in polymer melts, ensuring homogeneous foaming.
  • Supplier Reliability and Capacity: For industrial needs, it’s crucial to partner with a supplier that has a proven track record, adequate production capacity, and a stable supply chain. We pride ourselves on being a reliable manufacturer with substantial capacity to meet large volume orders.
  • Pricing and Value: While cost is a factor, it should be balanced against quality and reliability. Competitive pricing for high-purity PTSS ensures both economic viability and product performance. We offer attractive pricing for bulk purchases.
  • Technical Support and Documentation: A good supplier will provide comprehensive technical data sheets, safety data sheets (SDS), and responsive customer support to assist with application queries.
