Cadillac Plastic is a Swindon based convertor and distributor of plastic films and filmic adhesives. For over 40 years they have been providing customers with custom converted sheets and rolls of high-performance plastic films and filmic adhesives from major brands such as 3M, Lexan, MacDermid, Mylar, Transcontinental, and DuPont Tyvek. Cadillac Plastic provides a bespoke solution for every application from membrane switch panels to display screens, nameplates, and durable labels, with sheeting, slitting, guillotining, laminating and die cutting at no extra cost.
The team behind Cadillac Plastic have years of experience and knowledge in the industry, providing technical support that is second to none. For demanding, technical manufacturing applications there is no better company to offer support in finding the best solution. A dedicated sales advisor will always ensure the most efficient sheeting and slitting patterns to optimize material yields, reducing waste and costs.
Membrane Switch and Flexible Circuits
The benefits of membrane switches include ease of cleaning, solvent and chemical resistance, sealing ability, and their low profile. Membrane switches can be used together with other control systems such as touch screens, keyboards and back lighting.
Tactile feedback of keys can be provided by embossing the top layer or embedding metal snap domes, polyester domes or forming the graphic layer.
A hardcoated Polyester or Polycarbonate film on the top surface ensures durability whilst specialist 3M adhesives and spacer films bond the whole assembly together.

4. Membrane Switch Spacer: Adhesive Films and Tapes (e.g. 3M 7956)
5. Bottom Switch Circuit: High Performance Film
6. Adhesive Transfer Tape: Adhesive Films and Tapes (e.g. 3M 467)
7. Backer Board: Polyester Film; Polycarbonate Film
Choosing the Right 3M Adhesive for the Job
3M™ High Performance Acrylic Adhesive 200MP is a popular choice for graphic attachment and general industrial joining applications. It provides outstanding adhesion to metal and high surface energy plastics. This adhesive provides some initial repositionability for placement accuracy when bonding to plastics. It also performs well after exposure to humidity and hot/cold cycles.
• Up to 400⁰F short-term heat resistance
• Excellent solvent resistance
• Excellent shear strength to resist slippage and edge lifting
3M 467 (With 200MP Adhesive) Application Examples:
• Long term bonding of graphic nameplates and overlays
• Bonding metal nameplates and rating plates
• Bonding graphic overlays for membrane switches and for bonding the complete switch to the equipment surface.
• The adhesives bonding characteristics enable high speed processing of parts in the medical, telecommunications and electronics markets (medical components, durable labels, and flexible circuits).
• Bonding in lamination processes to industrial foams for rotary die-cutting of small gaskets for industrial and electronics markets.
3M 7956 (With 200MP Adhesive) Application Examples
• 3M™ Double Coated Membrane Switch Spacers are ideal for circuit separation
Why should I buy 3M adhesives from Cadillac Plastic?
Cadillac Plastic adds convenience and cost savings by supplying exactly the size and quantity you require, coupled with a short lead time – often next day. For multi-layer assemblies such as membrane switches, the overlay, heat stabilized Polyester for circuitry, spacer layers and adhesive tapes can all be purchased together in the correct size and quantity for that job.
Advantages of purchasing custom sizes and quantities:
• Cadillac Plastic converts materials from master rolls, minimising material waste and environmental impact.
• Buying no more than is required is the most cost-effective solution. Even ‘wasting’ 10-15% of a sheet is straight off the bottom line!
• When material is just the right size, the printing process can begin immediately, improving lead times.
• Materials can be supplied for specific jobs in the required quantities – this makes planning, internal tracking and allocation much easier.
• For multi-layer assemblies such as membrane switches, the overlay, heat stabilized Polyester for circuitry, spacer layers and adhesive tapes can all be purchased together in the correct size and quantity for that job.
• Purchasing ‘freshly’ converted material is better than using old, ‘out of date’ stock. This is especially important for adhesives.
ISO 9001 Quality Management Certification, held for over 30 years, is further evidence of dedication to quality and service. This is backed up by the ISO14001 environmental standard and ISO45001 for Health and Safety.
Not only does the team at Cadillac Plastic have their own product knowledge and expertise developed over many years of experience, the team at 3M are also on hand to provide help in offering solutions for ‘difficult to stick’ applications, for your evaluation. So, no matter what your project or application is, Cadillac is on hand with the appropriate product.
