What is PCTA material?
PETG/ PCTA/PCTG Glass polymers have the same clarity and high luster as glass, and are used for ultra-thick containers for products such as high quality cosmetics. They also have excellent chemical resistance, impact resistance and other characteristics.
What is thermoplastic polyester?
Thermoplastic Polyester Elastomers, or TPE, combine the properties of high performance elastomers and flexible polymers. Sometimes referred to as thermoplastic rubbers, these are high strength materials know for their ability to take repeated flex cycles and their resistance to many chemicals and oils.
What is thermosetting polyester?
Thermosetting polyester resin is obtained by crosslinking unsaturated polyester (UP) polymer with styrene. The UP consists of glycol and carboxylic acid such as fumaric acid and ortho- or isophthalic acid. Maleic anhydride is used as UP raw material, which isomerizes to fumaric acid during polyesterification.
What is unsaturated polyester resin used for?
Unsaturated polyester resins are among the most significant and industrially versatile thermosetting materials and are used in a wide range of applications, including automotive, marine, transport, building, construction, aerospace, and electronic devices due to their low cost, ease of fabrication, and high-performance …
Is Nylon A thermoplastic?
Nylon Characteristics Nylon is a tough thermoplastic with outstanding wear properties. Nylon is easy to machine and has high abrasion and impact resistance. It has excellent tensile and compressive strength and is an excellent electrical insulator.
Is nylon a thermoplastic or thermoset?
Nylon is classified as a “thermoplastic” (as opposed to “thermoset”) material, which refers to the way the plastic responds to heat. Thermoplastic materials become liquid at their melting point – a very high 220 degrees Celsius in the case of Nylon.
What is the difference between thermoplastic and thermosetting plastic?
Thermoplastics have secondary bonds between molecular chains. Thermosetting plastics have primary bonds between molecular chains and held together by strong cross-links. Thermosetting plastics have high melting points and tensile strength. Thermoplastic is lower in molecular weight, compared to thermosetting plastic.
What are the disadvantages of polyester resin?
Polyester resin has the following disadvantages:
- Strong styrene odour.
- More difficult to mix than other resins, such as a two-part epoxy.
- The toxic nature of its fumes, and especially of its catalyst, MEKP, pose a safety risk if proper protection isn’t used.
- Not appropriate for bonding many substrates.
How strong is polyester resin?
Once cured, polyester resin is water permeable, meaning water can pass through it eventually. The bonding strength of polyester resin is generally less than 500 psi.
What is the difference between nylon and polyester thread?
Similarly, polyester also can be made into a really popular polyester thread for the same uses. Both nylon and polyester are strong and light-weight thanks to their polymer-based construction. Nylon is stronger than polyester with more excellent stretchability.
What are the pros and cons of Nylon Vs polyester?
Comfort wise, both nylon and polyester are light-weight, quick-drying and smooth. Nylon tends to be warmer than polyester, and can often be more sweaty or cling more to the body. Any fiber can cause allergic reactions.
What is cationic-dyeable polyester?
Cationic-dyeable (or CD) polyester is a modified polyester. This type of polyester can be dyed in a different way, giving richer and more vivid color. Nylon is trickier to work with, which makes dyeing nylon a job reserved for very best professionals. Dyes are sometimes absorbed in an uneven way across nylon fabric, creating unwanted striping.
What is the difference between nylon and polyester bags?
Both nylon and polyester can be used for bags and backpacks. Nylon is more durable and weather -resistant, so it gets used for outerwear or outdoor gear. Polyester is better for companies with intricate logos who want to use bags for branding purposes.
