Purge Compounds for Thermoplastics

Product Details

(Click to enlarge image) Residue inevitably builds up after color and material changes. This often leads to frustrating production challenges for operators who use traditional methods to clean their thermoplastic processing equipment. These issues affect a variety of applications such as injection molding, extrusion, blown film, and extrusion blow molding. Presented as streaks, spots, and discoloration on finished parts, these problems contribute to an unstable process. This may result in higher scrap rates, more downtime, and lower quality of finished products. All things to avoid.

The value of switching to a high-performance purging compound is clear. Chem-Trend’s advanced purging compounds undergo rigorous testing and have the backing of global R&D resources. This ensures high-performance and high-quality characteristics remain constant.

Cost efficiency is an important consideration for your process. The use of a high-quality purging compound reduces the amount of time and material required to clean a machine from color and polymer contamination or material degradation. This contributes to a more stable production process and long-term financial gains.

Advanced purging compounds create a smooth transition between incompatible polymers and polymers with a wide processing temperature difference. They can also solve contamination issues when used to transition to clear or transparent polymers and when changing colors. This is necessary for hot runner molds and injection molding applications.
