FastelFilm PA250-LV Heat Activated PE Adhesive Film
FastelFilm PA250-LV can be used in applications where substrates can manage the higher heating temperature but require a higher continuous operating temperature. Through its higher operating temperature, it can be considered for more robust electronics, industrial, automotive or medical device/diagnostic applications. FastelFilm PA250-LV can be utilized as an adhesive interface bonding 2 substrates together or used as an interface perimeter sealing gasket.
As a dry-to-the-touch adhesive film, FastelFilm PA250-LV can be die cut to match a wide range of mounting and sealing applications areas. Once the adhesive pad is heated to or past its melt point temperature and cooled, the adhesive is set.

DOE Testing (design of experiment)
Preparation | Installation Guidelines
CORONA TREATED SURFACES Corona treated surface modification may be a benefit depending on substrate material type. Customer testing required.TEXTURED SURFACES Textured surface may be a benefit in order to create more surface area depending on substrate type. Customer testing required.ADHESION PROMOTERS It is important for customers to determine compatability of adhesive promoter treatment.
Full Bond Heating Temp
No set heating time required. Dependent on thermal conductivity of substrates and heating devices. Minimum melt point must be acheived. No complex ramp up and ramp down patterns required unless other materials require this during the heating process.
Cooling (set) Time
Adhesive should be allowed to adequately cool below its melt point before applying stress. It is recommended (not required) to maintain pressure during cooling to promote surface contact during this process. Forced direct air systems okay to accelerate cooling.
