Description

Stretchlon® 800 vacuum bag film has the highest elongation from all nylon films and is suitable for cure temperatures up to 204°C (400°F). When parts with multiple contours are vacuum bagged, Stretchlon® 800 is a good choice offering to stretch into most areas. Stretchlon® 850 is a high elongation film in tube form with a good softness which will conform to complex contours. Stretchlon® 800 & 850 are designed to remain more flexible than standard nylon films in low humidity conditions. They are recommended for epoxy and BMI resins.

Benefits

• Soft film is unaffected by low humidity, avoiding brittle film bag damage and vacuum loss.

• High elongation film stretches into complex shapes applying full pressure, improving part quality.

• Film is easier to work with and requires no conditioning, reducing time and cost of bagging.

Storage	Recommended Storage temperature is 5°C to 40°C (41°F to 104°F)at no less than 25% relative humidity. Store indoors in original packaging, do not stack rolls on end.
Usage	Optimal usage conditions are in a Relative Humidity range from 50% to 60%rh. Nylon based vacuum bag films are sensitive to humidity, remaining soft at higher %rh and at risk of become stiffer in low %rh, see "Hydrate bagging films" TDS.
