Thin slick plastic is a type of high-density plastic that is often used in industrial applications. It is known for its super slick properties, which make it challenging to secure to surfaces using standard adhesives. This plastic, identified as UHMW or HDPE, is commonly employed in CNC machining for specific customers. Its impervious nature requires unique attachment methods, such as drilling, countersinking, and screwing it into place. Thin slick plastic also finds utility in reducing friction, like under drawers, showcasing its versatility in various applications.

What You'll Learn
Adhesion
One method to enhance adhesion in plastics is surface treatment. This process increases the surface energy, making the plastic more receptive to bonding with adhesives, paints, or coatings. Plasma treatment, for instance, involves bombarding the plastic surface with ionized gas or "plasma," increasing the surface energy without altering the bulk characteristics of the material.
In some cases, roughening the surface of the plastic may hinder adhesion. Certain adhesives, such as pressure-sensitive adhesives (PSAs), may adhere better to a smooth, polished surface. Sandblasting or etching the plastic surface can increase the surface area, but the adhesive must be able to ooze into the created nooks and crannies for effective bonding.
When working with thin, slick plastics, the choice of adhesive is crucial. Structural adhesives, such as epoxies, urethanes, and silicones, can provide high-strength adhesion when cured with heat, light, or pressure. However, pure plastic adhesives may exhibit brittleness, and sharp impacts can cause bond failure. "Toughened" structural adhesives, such as rubber-toughened epoxies, offer improved impact resistance by redirecting the fracture propagation.
Additionally, double-sided tapes, such as high molecular weight polyethylene tapes, can be used for specific applications. These tapes are effective in reducing friction and have been successfully used in table saw jigs and under drawers. However, they may not be suitable for industrial applications or high shear loads, as they tend to creep over time.

Antiskid plastic sheets
Anti-skid plastic sheets are a type of high-density plastic designed to provide traction and grip in slippery environments. They are commonly used in marine applications such as decking, dock boxes, and swimming platforms, where their anti-skid texture helps to improve safety by reducing the risk of accidents. These sheets are made from a material known as HDPE (high-density polyethylene) or UHMW (ultra-high-molecular-weight polyethylene), which is known for its strength, durability, and resistance to water and humidity.
One popular product in this category is the King StarBoard® AS, which comes in a bright white colour and features a dot non-skid texture. This product is designed to be easy to fabricate using standard woodworking tools and is marketed as an environmentally stabilized marine plastic sheet that will not rot, swell, splinter, or delaminate when exposed to water or humidity. It is commonly used in locations where grip is critical, such as deck hatches and steps.
The installation and adhesion of anti-skid plastic sheets can be challenging due to the impervious nature of the material. In general, mechanical fasteners such as drilling, countersinking, and screwing are recommended, especially if the sheet will be subjected to shearing forces. While adhesives and tapes can be used, they may not provide a secure long-term solution, especially in industrial applications. Sandblasting or etching the surface of the plastic can increase adhesion by providing more surface area for the adhesive to grip onto.
Anti-skid plastic sheets offer a reliable solution for improving safety in slippery areas, making them a popular choice for marine and other outdoor applications. With their durable construction and anti-skid properties, these sheets provide a stable and secure surface, even in wet or humid conditions.

CNC machining
When CNC machining thin, slick plastic, there are several important considerations to keep in mind. Firstly, it is crucial to secure the material firmly to the CNC machine to prevent flexing during the cutting process. Double-sided tape, adhesive spray, or a vacuum hold-down can be used to achieve this. Secondly, the speed of the cutting tool must be carefully controlled to avoid generating excessive friction, which can melt the plastic and wear out the tool.
Different types of plastics have unique properties that make them more or less suitable for CNC machining. For example, Delrin, a semi-crystalline thermoplastic, is known for its high stiffness and rigidity, making it an excellent choice for parts requiring dimensional accuracy and tight tolerances. However, Delrin's slippery surface makes it difficult to glue, and it has internal stresses that can cause warping in thin sections. ABS, on the other hand, is a widely used general-purpose plastic known for its high impact strength, toughness, and electrical resistance. It is easy to finish and can be painted, glued, or welded, making it a popular choice for prototyping.
Acrylic, also known as Plexiglass, is another commonly machined plastic. It is versatile, shock-resistant, and more resilient than glass. However, it is brittle and tends to crack or shatter under stress. Thinner walls in acrylic components are more prone to brittleness, and machined surfaces tend to lose their transparency, becoming frosted and translucent. Therefore, special attention must be paid to wall thickness and transparency requirements when machining acrylic.
In conclusion, CNC machining of thin, slick plastics requires careful consideration of the plastic's properties, secure workholding, and controlled cutting speeds to achieve precise and accurate results without damaging the material or the tool.

UHMW tape
UHMW (Ultra-high Molecular Weight) Polyethylene Tape is a thin, slick plastic tape with a high bond adhesive that can be used for a variety of applications. It is known for its resistance to abrasion and impact, making it ideal for surface protection and friction reduction. The tape is often used for lining sliding surfaces such as drawers and bearings to reduce squeaking and rattling caused by vibration or wear.

HDPE
High-density polyethylene (HDPE) is a thermoplastic polymer produced from the monomer ethylene. It is also known as polyethylene high-density (PEHD) and is sometimes called "alkathene" or "polythene" when used for HDPE pipes.
One of the key advantages of HDPE is its high malleability, rigid strength, and corrosion resistance. It has a high melting point, making it suitable for use in high-temperature environments. Additionally, HDPE is known for its outstanding tensile strength and resistance to mould, mildew, and rotting. It can withstand most strong mineral acids, bases, and naturally occurring chemicals in the soil.
In terms of its physical characteristics, HDPE is a super slick material that is challenging to secure to surfaces. It can be secured by drilling, countersinking, and screwing into place, especially when subjected to shearing forces. It can also be cut with woodworking drills and shaped with a standard block plane.

Frequently asked questions
Thin slick plastic is used in industrial applications to bond materials together. It is also used to reduce friction for jigs and under drawers.
The best method to attach thin slick plastic to a workbench is by drilling, countersinking, and screwing it into place. This is because the material is impervious and difficult to secure.
High molecular weight polyethylene tapes with adhesive on one side can be used to reduce friction for jigs. However, sandblasting or etching the plastic increases the surface area for the adhesive to stick to.
