Tremendous Physical and Chemical Properties Of PVC

Polyvinyl Chloride or better known as PVC among the masses is a breakthrough material in the plastic segment with a wide range of usage possibilities in the construction, transportation, electronics, packing and healthcare industries. PVC wire is considered to be the best for use keeping in mind the durability and effectiveness of the material.

If we compare it with other thermoplastics then the method to prepare PVC is significantly different, it uses two primary materials namely common salt and hydrocarbon feedstocks. While the former comprises of 53% composition in molecular weight the later uses 43% in the mix.

PVC has the following physical properties to its advantage:

High Tensile Strength
It has a tensile strength of 2.60 Nmm² that makes it a perfect material to be integrated in the wiring industry.

Impact Strength
PVC has an unmatched notched impact strength of 2.0 – 45 Kj/m² making it a preferred choice for various applications.

Coefficient of Thermal Expansion
No material can stand strong the in the wiring industry without a good thermal coefficient in terms of expansion, in this case being 80 x 10-6

Apart from the above mentioned physical attribute PVC has a high max cont use temp of 60 degrees with  an impressive density of 1.38 g/cm3. However, the positive qualities do not end here. On a scale of 1-4 where 1 being poor and 4 being very good PVC has the following implications in chemical resistance.

Dilute Acids– Score of 4- Verdict: Very Good
Dilute Alkalis– Score of 4- Verdict: Very Good
Greases and Oils– Score of 3- Verdict: Good
Alcohols– Score of 3- Verdict: Good

When talking about hydrocarbons PVC has very resistance to aliphatic hydrocarbons while it works fairly for aromatic and halogenated hydrocarbons. Hence, due to its unmatched physical and chemical attributes PVC is considered as one of the best materials to be used in the wiring industry and it is advisable to use it in any new projects or while replacement in the old ones.

All You Need To Know Before Owning A Heat Shrink Gun

Heat Shrink gun is commonly used to provide termination, insulation, sealing, strain relief for cables and identification. It has many uses in electric, electronic, telecommunications, cable management, and virtually all other industries, and there are many variations to meet different needs: less costlier options for light, unexposed use, high temperature versions for general  and automotive purpose, military and aerospace applications, and adhesive lined heat tubing for tight seals that keep out moisture and dust.Heat Shrink gunThe most common method for contracting heat shrink is the heat gun. Heat guns range from fixed temperature versions with moderate heat for general use to variable temperature models with digitalized readouts. The heat shrink oven is a costlier and not easily portable but is more energy efficient model.

Heat Guns at Work and home

For craft or household use, a small low-powered heat gun is usually adequate. In an industrial setting or work , a higher temperature level and more features and controls may be required. Here are a few of the many commercial uses or household or heat guns.

How To Choose Heat Gun Model

An important part of choosing a heat gun is knowing how it will be used. Since different kinds of projects require different temperature levels, so buyers need to consider which tasks they plan to fulfill with their heat gun. This will help them finding a product that provides the appropriate temperature range.

Usually most household projects require low amount of heat and construction, major repairs and welding require higher levels. If the gun is to be used for a variety of tasks, then better choose a model with different heat settings and a wide temperature range is advisable.

Features and Options  For Heat Gun

After deciding on temperature requirements of heat guns, shoppers must narrow down their choices by available features and price.
