Polycarbonate is a durable material, with high impact-resistance. The characteristics of polycarbonate compare to those of polymethyl methacrylate, but polycarbonate is stronger and will hold up longer to extreme temperature. Polycarbonate is highly transparent to visible light, with better light transmission than many kinds of glass.
Unlike most thermoplastics, polycarbonate can undergo large plastic deformations without cracking or breaking. As a result, it can be processed and formed at room temperature using sheet metal techniques, such as bending on a brake. Even for sharp angle bends with a tight radius, heating may not be necessary. This makes it valuable in prototyping applications where transparent or electrically non-conductive parts are needed, which cannot be made from sheet metal.
Cast acrylics have thermal stability, high resistance to crazing when exposed to solvents, wider thermoforming range than extruded acrylic. Cast acrylic has better ability to be reworked hot and it is known for its superior surface finish and optical properties. Also cast acrylic is more scratch resistant than extruded acrylic. Cast acrylic is also preferred over extruded in applications that require machining, such as turning on Engine Lathe or milling/drilling.
This type of acrylic is often used for aquariums, awards, financial tombstones, trophies, corporate gifts, and other products that require shaping or machining. It tends to be more clear and made to a high quality standard.
An ideal material for building projects to replace worn-out teak or plastic laminates or plastic parts on your boat. Starboard is high-density polyethylene which is stabilized to resist saltwater, chemicals, and sunlight. It will not rot, splinter, swell or delaminate! It retains its original color indefinitely, and doesn’t require refinishing. The scuff-resistant surface cleans easily and quickly with a scrub brush and light abrasive cleaner. It has a beautiful matte surface texture, and ranges in thickness: 1/4", 1/2" and 3/4".
Starboard is great for projects like cutting boards and bait boards, shower floors, companionway hatch boards, sink covers, cabinets and electronics boxes, bait wells, table tops and literally hundreds of other applications.
Starboard needs no painting, finishing, or maintenance. It is widely used by professional boat builders. If your boat was built in the last 15 years, it probably has starboard parts somewhere on board.
