Selecting Plasticizers for Adhesives and Sealants
Plasticizers may also be one of the least expensive additives used in adhesives and sealants, and they can be used in relatively large concentrations depending on the application and formulation (up to 100 parts by weight per 100 parts of the base polymer). For these reasons, they are sometimes used as extenders for cost-reducing purposes.
Plasticizers Market Size, Industry Share, Forecast 2030
The manufacturing facility has nameplate capacity of 60000 tons per year. In May 2016, Eastman Chemical company expanded its range of non-phthalate plasticizers under the brand name VersaMax. The new product Versamax Plus is the second product installment of the company. REQUEST SAMPLE. SPEAK TO ANALYST.
Plasticizer - an overview | ScienceDirect Topics
Plasticizer efficiency is used to describe the ability of a plasticizer to make the product softer and is reported as a ratio of the slope of the hardness versus plasticized concentration to the slope of that found for DOP. The relationship of hardness and plasticizer concentration expressed in phr (parts per hundred resin) is shown in Figure 3.
Guide to Coefficient of Friction Testing - Industrial Physics
It is also known as ASTM D1894 and is the standard testing method for determining the static and Kinect friction of films and plastic coatings. Coefficient of friction testing methods. One of the most common COF testing methods to find out the static friction of a surface is to measure how much force it takes to move a sled placed on that surface.
- What is coefficient of friction?
- The coefficient of Friction of a material is the measure of the sliding resistance of a material over another material. In the case of thermoplastics the mating part is normally steel.
- What is the coefficient of friction of plastic against dry steel?
- The chart below shows some typical values for a variety of plastics against dry steel. Most polymers have coefficients of friction in the range 0.2 to 0.6 but the fluorocarbons generally have lower coefficients of friction than this range.
- Does PTFE have a low coefficient of friction?
- While some materials such as PTFE have extremely low coefficients of friction (around 0.05 against dry steel) even these can be improved by the introduction of effective lubrication.
- Why is lubrication effective if a material has a low coefficient of friction?
- Lubrication is effective even for materials with a very low coefficient of friction because the lubricant layer not only greatly reduces the coefficient of friction but also reduces the surface damage caused by the asperities rubbing together.
- What is a 'dynamic coefficient of friction'?
- This is a very simplistic statement and quite misleading for brake materials. With many brake materials the dynamic coefficient of friction quoted is an "average" value when the material is subject to a range of sliding speeds, surface pressures and most importantly operating temperatures.
- What is a static coefficient of friction?
- If the static situation is considered at the same pressure, but at ambient temperature, then the static coefficient of friction is often significantly LOWER than the average quoted dynamic value. It can be as low as 40 - 50% of the quoted dynamic value. Kinetic or sliding frictional coefficients are used with relative motion between objects.
