Details
Highlights
- Excellent for foam and gasket attachment, HSE and LSE plastics such as polyethylene
- Quick flowing adhesive delivers high initial adhesion for faster lamination
- .5 mil PET film carrier adds dimensional stability and easier handling during slitting and die-cutting
- 3M™ Adhesive 300 aggressively bonds to many surfaces, including plastics like polyethylene
- 55# densified kraft liner makes for easy release
3M™ Double Coated Tape 444 features our 3M™ Adhesive 300, a medium-firm acrylic adhesive ideal for joining materials that are smooth, thin and have low residual stress. It is excellent for foams and LSE plastics such as polyethylene, as well as HSE plastics. Adhesive is applied to both sides of a .5 mil PET film which adds structural stability. This tape features a 55# densified kraft liner.
A Double Coated Tape for Foams and LSE Plastics
Excellent for textured plastics, foams, fabrics and coated papers, 3M™ Double Coated Tape 444 features 3M™ Adhesive 300 on a.5 mil polyester (PET) film carrier. The medium-firm acrylic adhesive delivers high initial and final adhesion for efficient laminating procedures. The durable polyester film carrier between the adhesive layers improves the handling and strength of the tape, and adds stability during processes such as die-cutting and slitting. The adhesive is applied at 1.4 mils on the liner side and 2 mils on the face side for effective wet-out. The 55# densified kraft paper release liner makes for fast, efficient application.
About Our 3M™ Adhesive 300
3M™ Adhesive 300 is a medium-firm acrylic adhesive system featuring both high initial adhesion and good UV and chemical resistance and strong holding power. The design of the adhesive results in a balance between shear strength, high initial adhesion and temperature performance. Shear strength is the measure of pull force directed across the bonded surface, forcing the two surfaces to slide over each other. The formulation gives 3M™ Adhesive 300 a consistently strong bond across a range of temperatures up to 250°F/121°C short term.
Recommended Applications:
Medical diagnostic test strips
Plastic film lamination/bonding
Splicing
Foam lamination
Gasket attachment
What is Double Coated Tape?
In general, double coated tape is composed of a paper, film, or tissue carrier that is coated on both sides with pressure sensitive adhesive. The adhesive is protected by a peel-away liner that is removed at the time of application. These tapes can be applied by hand or with a dispenser. Double coated tape dispensers are available in a variety of configurations ranging from manual to fully automatic. Applications for double coated tape are found in electronics, automotive, aerospace, general industrial, and fabrication markets.
