Commercial thermoplastic processing equipment requires fast, effective, and cost competitive means of cleaning and/or purging plastic resin.
RapidPurge has been the top performing purging compound for over 35 years and experienced industry insiders know that our products defeat the most demanding hostile thermoplastic processing challenges including carbon buildup and the resistant’s of color changeovers.
We first introduced commercial purging technology to the United States and still retain excellence in customer service and performance. Our product is only successful if our customers meet their desired goals in performance and costs which is why you can choose your requirements.
We offer an extensive range of purging compounds that provide numerous options in achieving purging performance/cost objectives in diversified processing applications.
The choices include all major preference categories from heavy duty chemical purging to quick change mechanical purging. These choices also include selections in shut-down grades for material stabilization.
RapidPurge is unique in offering custom purging solutions. Working with our Technical Support department, a custom purging grade can be developed for your specific application. A unique part number will be assigned to your custom blend so that you can re-order with maximum convenience.
≡ Features and Benefits
Heavy-duty Chemical Agents
Our proprietary chemical formulation adds an extra punch for heavy-duty, challenging purging operations.
Activated Foaming Agent
Selective RapidPurge grades include a heat-activated foaming cleaning agent to clean hard-to-reach negative flow areas.
Pellet Form Factor
The RapidPurge proprietary pellet manufacturing process ensures that the chemical potency/reactivity of the compound is preserved for purging.
Excellent shut-down properties clean and prevent degradation, and complement efficient start-ups.
The pre-mixed products include a universal carrier resin, providing the ultimate in convenience and handling.
Concentrates can be mixed at your location with your resident polyolefin resin to provide a very cost-effective purging compound. Concentrate to be mixed with resin of equal or greater value in viscosity than resident resin being purged. Depending on the Concentrate chosen, mix ratios can vary between 2:1, 4:1, or 5:1.
Because your production resin is used as the carrier and no other resin is added to the RapidPurge product, no foreign resin is introduced into the molding equipment.
Concentrate to be mixed with resin of equal or greater value in viscosity than resident resin being purged.
When necessary, temperatures can be raised to maximum level of resident resin allowing for a short soak cycle during purge for highly demanding applications. Varying screw speed as RapidPurge is being run through will maximize scrubbing action and agitation inside the barrel.
Designed and made specifically for you to combat your own enemies. A private part number will be assigned to your custom blend so that you can re-order with maximum convenience. Your custom blend will be incorporated into our manufacturing flow, assuring you of complete consistency from order to order.
