What Dyna-Purge does

Dyna-Purge is a manufacturer of engineered, non-chemical, non-abrasive purging compounds for plastics processing machinery, operated as a product line of Shuman Plastics, Inc. and headquartered in Depew, NY. The company sells a portfolio of specialized formulations—including Dyna-Purge L (low viscosity, high cavitation), D2 (broad temperature range, versatile), E4 (high-temperature engineering resins up to 715°F, 4X technology), A (polypropylene-specific, Hybrid technology), K (low temperature/low durometer), C (clear/transparent, low residue), and RF—alongside legacy grades such as F2 (3X dual-action technology). These compounds are designed to remove resin, color, carbon, additives, and impurities from injection molding and extrusion equipment by acting on process boundary layers and negative flow/stagnation points without abrasives or chemicals, and are positioned as FDA-compliant, recyclable, and requiring no mixing or soaking.

The company's go-to-market combines direct field and inside sales in the US with an international distributor network accessed via a 'Find Your Distributor' portal and an active 'Distributors Wanted' program. Revenue is generated through one-time consumable sales priced on a quote basis with a 'low cost-per-purge' economic model, supported by free sample requests, case studies documenting outcomes such as 30% savings, 75% compound consumption reduction, and $189K+ annual savings, an interactive savings calculator, training videos, and technical troubleshooting resources. Target customers include injection molders (cold/hot runners, stack molds, automation), extrusion operators (profile, sheet, blown/cast film, compounding, blow molding), and processors of high-temperature engineering resins (PEEK, PEI, PPS, PPA, PSU) across plastics manufacturing and research environments.

Founded circa 1982-1983, Dyna-Purge operates with 11-50 employees under Shuman Plastics, Inc. and leverages its parent's US-based manufacturing infrastructure. The company holds registered trademarks for its brand and slogans, maintains an active SPI (Society of the Plastics Industry) association affiliation, and relies on proprietary formulation technology rather than AI/ML capabilities as its core differentiation.

Core offering

Dyna-Purge manufactures and supplies engineered, non-chemical, non-abrasive purging compounds used to clean plastic processing machinery such as injection molders and extruders. The compounds remove resin, color, carbon, additives and impurities during color changes, resin transitions, and preventive maintenance, and are sold directly and through international distributors.

Product overview

Dyna-Purge is a manufacturer of engineered purging compounds for plastic processing machinery. The company offers a portfolio of leading products and legacy products. Leading products include: Dyna-Purge L (low viscosity for high cavitation and automation), Dyna-Purge D2 (broad temperature range, most versatile), Dyna-Purge E4 (high temperature engineering resin formula using 4X technology for temperatures up to 715°F), Dyna-Purge A (polypropylene-specific formula using hybrid technology), Dyna-Purge K (low temperature/low durometer formula), Dyna-Purge C (clear and transparent resin formula with low residue), and Dyna-Purge RF. Legacy products include Dyna-Purge F2 (using 3X technology for dual-action cleaning), Dyna-Purge M, Dyna-Purge F, and Dyna-Purge SF. All products are designed for injection molding and extrusion applications to remove resin, color, carbon, additives, and impurities without abrasives or chemicals.

Products and services

• Dyna-Purge L Low viscosity purging compound designed for high cavitation, stack molds, or automation with continuous molding. Temperature range: 290°F – 625°F (143°C – 329°C). Used in injection molding (cold and hot runners) and extrusion (profile, sheet, blown and cast film, compounding, blow molding).
• Dyna-Purge D2 Broad temperature range purging compound described as the most versatile Dyna-Purge grade. Temperature range: 320°F – 625°F (160°C – 329°C). Used in extrusion (profile, sheet, cast film, compounding, blow molding).
• Dyna-Purge E4 High-temperature engineering resin purging compound incorporating 4X technology for reduced purge oxidation and lower smoke emission. Temperature range: 575°F – 715°F (302°C – 379°C). Designed for high-temperature engineering resins including PEEK, PEI, PPS, PPA, PSU. Minimum clearance: 0.030 inch or 0.75 mm. Used in injection (cold and hot runners) and extrusion (profile, sheet, cast film, compounding).
• Dyna-Purge A Polypropylene (PP) specific purging compound using hybrid technology with a custom carrier matrix and unique agents. Temperature range: 320°F – 500°F (160°C – 260°C). Designed for PP and PP-based resin systems. Used in injection (cold and hot runners) and extrusion (profile, sheet, cast film, compounding, blow molding).
• Dyna-Purge C Clear and transparent resin specific purging compound with low residue formula. Temperature range: 380°F – 590°F (193°C – 310°C). Designed for processors that need to purge without leaving residue that would compromise clarity.
• Dyna-Purge K Low temperature range purging compound with a low durometer specific formula. Temperature range: 290°F – 550°F (143°C – 287°C). Used in extrusion (profile, sheet, cast film, compounding, blow molding).
