Tubular Plastic Anchors - Fastener Mart
#10 or #12 should work with 3 inch deck screws to mount 2by4 2x4 on wall.
anchor should be 2 inches long.
1.5 inch thick 2by4.
2 inch hole in concrete.
That leaves 0.5 inch leeway for the screw to dig into the 2by4.

Crystalline vs. Amorphous PET;;;
All PET materials are hygroscopic, so exposure to a humid environment will cause them to absorb moisture. This moisture causes a cleavage in the polymer chain during melt and results in a degradation of the physical properties of the product produced.

Virgin PET
Virgin PET is usually in a crystalline state (indicated by its white color) when it is purchased from a supplier.
Reground PET
Regrind PET material is usually not crystalline, but amorphous and clear in color.
Agitating the material while heating it to a temperature of about 180˚ F will convert the material from its amorphous state to a crystallized state, ready for drying. We call this process crystallizing but technically, it is a re-crystallization of the material.

What's the difference between Crystalline and Amorphous States?;;;;;;

What's the difference between Crystalline and Amorphous States?;;;

The nature of crystalline and amorphous polymer states is often misconstrued and misused. The term amorphous means to have no defined shape, or an easily altered shape, like a liquid or a rubber. Crystalline, on the other hand, insinuates that there is a regular, defined pattern to the molecular aggregates --- crystallized carbon forms a substance we call “diamond”. These terms are used to define two separate “solid” states that exist particularly in polymers. The confusing part is that they coexist in many polymers --- the so-called semi-crystalline polymers.

The amorphous nature of polymers is analogous to a plateful of spaghetti --- loose and randomly coiled. While the crystalline state is more like the uncooked spaghetti in the box --- the chains are all tightly bundled and ordered in the same direction.

In a polymer, these two states coexist,

1. Create A CAD Drawing

* Have an idea or sketch with your dimensions and expectations for the design
* Design the product with the computer program like CAD

2. Plan and Choose the Correct Plastics, Expectations

* Ask Specific Questions:
* What are the conditions under which the product will be used such as temperature, moisture, ultraviolet exposure, chemicals, electrical resistance, physical properties, colorability, and resistance to scratching?
* What tolerance requirements are expected in the performance of the product?
* WIll the product be under any stresses, exposure to impact, bending or gliding?
* Is color matching a factor?
* What is the cost per inch of material? Its weight?
* Cover approval requirements-underwriters, Pure Food Administration, military, and others.
