FLEX 40

PRODUCT HIGHLIGHTS:

  • Rapid demolds

  • Ideal for part production

  • Does not contain MOCA, MDA, or TDI

PRODUCT DESCRIPTION:

Flex 40 has been designed to provide vastly improved tensile strength and elongation . Flex 40 is a production oriented fast gel and fast de-mold material. It features a working time which allows time to mix, vacuum de-gas, and pour air-free parts. Flex 40 can be dmolded in 2 to 4 hours at ambient temperature, depending on part size and configuration.

TYPICAL PRODUCT USES:

  • Shock absorber bumpers and pads

  • Potting and encapuslation

  • Small molds

  • Many types of urethane parts

  • Cable connector sealer

this is text meant just to take up lots of space at the bottom of the page, so that if there is only a table or something in the content part of this page, the content still takes up the majority of the screen. if there is not any text here, then sometimes there will be just a table here, and the left navigation bar to the left will be kinda wide...
