It can be secured by drilling, countersinking, and screwing into place
When it comes to securing super slick high-density plastic, such as UHMW (HDPE), the process can be challenging due to its impervious nature. The recommended method for attaching it to a workbench or any other surface involves drilling, countersinking, and screwing it into place. This method ensures a secure hold, especially when the plastic is subjected to shearing forces.
Drilling into UHMW plastics requires the use of woodworking drills, and it's important to note that sharp edges can be addressed with a standard block plane and a well-sharpened blade. The edges themselves can be quite sharp, so caution is advised. Additionally, drilling round holes for the middle of pieces and routing slots for the outside can help accommodate thermal expansion, a common issue with plastics.
While double-sided tapes may be considered for attachment, they tend to creep over time and are not ideal for high-shear applications. However, industrial PSA (pressure-sensitive adhesive) tapes have shown promising results in bonding similar materials, although thin sections of UHMW may pose challenges due to thermal expansion and contraction.
It's worth mentioning that polyethylenes, including UHMW, are notoriously difficult to bond. Industrial processes involve surface oxidation to create carboxylic acid groups for bonding, but these methods are not recommended for non-professionals due to their dangerous nature. Therefore, for most applications, drilling, countersinking, and screwing remain the most reliable methods for securing super slick high-density plastic.
