Dear <<First Name>>,
Welcome to the latest 4PLAS newsletter, this month we would to discuss the benefits of using an effective purge.
Many plastics processors use a variety of purge materials and speciality products which range from Polypropylene to speciality liquid & granular purges, the prices and effectiveness of these purges vary dramatically, in some case too much or too little is used and in other cases the process has to be repeated several times.
Reasons for purging machines differ greatly with the main reasons being:
Our wide range of thermoplastic compounds has enabled us to look closely at the purging processes used and then to consider the problems carefully, we found that in many cases the purging process is ineffective and proves to be expensive or inefficient, often requiring large quantities of commodity polymer or using a specialty purge that is prohibitively expensive.
- Contamination in finished parts during a run
- Colour changes
- Machine shut down
- Polymer change
- Regular planned purging to prevent build ups during production.
You may feel that purging is a necessary evil and never quite feel in control of the cost or effectiveness, many companies persist with the same purging method having reached a compromise process that kind of works and is just about bearable on cost.
Over the last 10 years 4PLAS has been working with our customers to achieve cost effective purging solutions with the introduction of our 4PURGE® purging compounds, these highly effective products have been developed using a polymer base with scrubbing and foaming additives.
