There are certain polymers out there that can be classified as millable or machinable. When millable plastics are needed for the aggressive environments encountered by oil and gas equipment, the challenge to find a suitable polymer becomes even harder.
As you know, polymers behave very differently from metals. One aspect of that behavior involves the glass transition temperature. In this blog post, we are going to focus on the glass transition temperature of thermoplastics.
This blog post represents the second installment in a series of posts on thermal analysis techniques for polymers. In part 1 we discussed differential thermal analysis, thermomechanical analysis, and dynamic mechanical analysis.
In this blog post, we are going to start a discussion about the most common thermal analysis techniques used to investigate the properties of polymers. In part 1 of this series, our focus will be on:
- differential thermal analysis
- thermomechanical analysis; and
- dynamic mechanical analysis
This discussion will include how these tests are performed and what kind of properties can be determined from the resulting data.
Polyimide, typically abbreviated as PI or referred to tradenames such as Vespel, Plavis and Duratron-PI, is the second most powerful high temperature engineering polymer on the market today, right behind Celazole. In this blog post, we are going to discuss the characteristics and uses of this powerful high-performance polymer.
Extreme polymers are known for their performance at high temperatures that other polymers just cant handle. In this blog post, we’ll take a look at PBI the highest performing thermoplastic on the market today.
High temperature polymers are divided into two categories: amorphous and semi-crystalline.
