Why do We use ASA Material in the Pool Heat Pump?

Pool Heat Pump- ASA or ABS Material

As we all know, ABS resin (acrylonitrile-butadiene-styrene copolymer, ABS is the abbreviation of Acrylonitrile Butadiene Styrene) is one of the common plastic materials. It is a kind of thermoplastic polymer material with high strength, toughness, and easy processing. After molding, its glass transition temperature is about 105°C (221°F). ABS is amorphous and therefore has no real melting point. ABS plastic is made of ABS resin.

ABS plastic has the common characteristics of the three components. A makes it resistant to chemical corrosion, heat resistance, and certain surface hardness, B makes it have higher elasticity and toughness, and S makes it have the processing and molding characteristics of thermoplastics and improve electrical properties. Performance. Therefore, ABS plastic is a kind of “tough, hard, and rigid” material with easily available raw materials, good comprehensive performance, low price, and a wide range of uses.

So why suddenly abandon the traditional ABS to use this series of new materials?
After all, ABS has been the “preferred” material for our plastic electronic enclosures for decades in the application of pool heat pump-and it is still true for many tried and trusted models.Alsavo pool heat pump.

Acrylonitrile styrene acrylate (ASA), also known as acrylic styrene-acrylonitrile, is an amorphous thermoplastic made of acrylic rubber, modified styrene, and acrylonitrile. It was developed as an alternative to acrylonitrile butadiene styrene (ABS), but it has improved weather resistance and is widely used in the automotive industry.

ASA is very similar in structure to ABS. Technically speaking, ASA not only maintains the main characteristics of ABS but also combines the advantages and weather resistance of PMMA. The difference between acrylic rubber and butadiene-based rubber is that there is no double bond, which makes the material’s weather resistance and ultraviolet radiation resistance about ten times that of ABS, and has a higher long-term heat resistance and better heat resistance. Chemical. ASA is more resistant to environmental stress cracking than ABS, especially alcohol and many cleaning agents. The glass transition temperature of ASA is lower than that of ABS, which is 100°C and 105°C, respectively, which provides the material with better low-temperature performance.

ASA has high outdoor weather resistance; when exposed outdoors, it maintains gloss, color, and mechanical properties. It has good chemical resistance and heat resistance, high gloss, good antistatic properties, toughness, and rigidity. It is used in applications that require weather resistance, such as pool heat pump frame, or outdoor furniture.

Compared with polycarbonate, ASA has a higher resistance to environmental stress cracking and a lower yellowing rate in outdoor applications. Compared with polypropylene, ASA has lower molding shrinkage (0.5% vs. 1.5%), higher stiffness, impact resistance, heat distortion temperature, and weather resistance. Alsavo pool heat pump.
