Scapa 3130 Chroma Key Tape is a polyethylene coated waterproof cloth tape, single coated with a pressure sensitive rubber adhesive. It is a matte finish AV cord tape primarily used in the entertainment industry to match blue screens and green screens. Besides this chroma key tape being used for color keying it can also be used for bundling and holding of wires and cables since it removes easily from surfaces without leaving any residue or marks. Scapa 3130's matte finish prevents the reflection of light, making the product ideal for applications where low light reflectance is essential, especially in theaters, film sets, and studios. The tape can also be used for color coding and identification; floor marking; securing scenery and backdrops to different surfaces; and masking applications such as unwanted film set items. The tape has excellent tear properties; is highly flexible and conformable; has easy unwind, and has good strength and tack.

hot melt rubber (synthetic)
Offers the widest range of application flexibility available. Exhibits excellent processing performance whether manually or automatically applied. Has superior tensile strength, adhesion properties and holding force which ensures consistent, reliable seals. Hot melt adhesive will bond faster to a surface which is referred to as quick-grab or quick-stick. It typically has higher tack (will feel stickier to the touch), but is also softer. It has lower heat resistance, shear resistance, and sometimes UV resistance than an acrylic adhesive. NOTE: it is called hot melt because the adhesive is applied hot by the manufacturer and then hardens as it cools (you do not need to apply heat to the tape yourself).
natural rubber
Properties are similar to that of hot melt rubber, but natural rubber often holds where other adhesives won't (recycled fibers, dust, cold, heat and heavy loads). It provides good overall adhesion and moisture resistance.
acrylic
Offer excellent performance, especially for applications in temperatures less than 40°F and greater then 120°F. It provides excellent clarity, has high shear strength, is usually more permanent/durable even when exposed to moisture, and it ages well over extended periods in fluorescent and sunlight. Since it remains clear for the life of the application and does not yellow over time it is ideal for applications such as sealing white cartons. While it has good initial adhesion it does take 24-48 hours to cure and to achieve its maximum bond strength (has gradual adhesion buildup). Another difference between hot melt rubber and acrylic adhesive is if you fold tape over making the two adhesive sides touch the acrylic adhesive will remain attached to the carrier (e.g. paper, film) while a hot melt adhesive will stick to itself and pull off of the carrier. It is the best choice for clarity, UV resistance and aging characteristics.
silicone
Is great for extreme temperature applications since silicone adhesive can work in continuous operating temperatures from -100°F to 500°F. They also exhibit good chemical resistance, retain electrical properties, and remove cleanly with little or no residue.
zinc oxide
Zinc oxide based adhesive formula is a skin-friendly adhesive which is commonly used on sports medicine tapes.
