Bathtubs Materials: Acrylic is the Best Bathtub Material

In plastic industry, acrylic is polymethyl methacrylate, shorten as PMMA, it’s a kind of engineering thermoplastics with very excellent overall performance and thought to be the best bathtub material.

In 1872, Polymerization of acrylic acid was discovered; polymerization of methyl methacrylate became known in 1880; the study of synthesis of poly-acid ester was completed in 1901; In 1927, people attempted to start industrialization manufacture of the aforementioned synthesis method. Till 1937, the successful development of methacrylate on industrial manufacturing enters to a large-scale manufacturing. During WW II, because acrylic has excellent strength, toughness and transparency, it is firstly applied to the windshield of the aircraft and cab driver's vision mirror of tank. In 1948, the birth of the first acrylic bathtub marked the beginning of a new milestone of acrylic application.

The official name of acrylic bathtub is fiberglass reinforced plastic bathtub.The surface material is a methyl ester C, opposite covered with fiber glass, coated with resin to enhance.The color of acrylic bathtub should be thoroughly uniformed, and the surface is smooth, non-hierarchical and bubbles etc. Its surface thickness normally above 3mm, and its combination with fiber glass must be very solid without peeling.

Heat transfer of acrylic bathtub is very slow, so, acrylic bathtub has good warm keeping, there is no “cold” feeling while touch the body. Comparing with cast iron bathtub and steel bathtub, acrylic bathtub has a kind of warm and soft feeling and won’t ache the body. Since acrylic has very good re-producing performance, only acrylic can be used to manufacture luxury whirlpool bathtubs.

Acrylic is a kind of by-product which extracted from deep-sea oil. After carefully study the acrylic, you will find it not so magical; it is actually a kind of organic glass.

Although acrylic is a kind of glass, it is not so “fragile” as glass. Its impact resistance is 200 times stronger than ordinary glass, almost does not break. Its load-bearing changes with thickness, the thicker the more solid. Acrylic is not only hard, but also flexible. It’s very suitable for modeling; corner curvature can be achieved through technology. It’s better insulation than glass. The only shortcoming of acrylic is most afraid of sharp objects to scratch. However, the scratches are easily to repair, just wipe by white toothpaste, the scratch could be disappear immediately.

There are three kinds of acrylic sheets on the bathtub market: special sanitary acrylic sheet, ordinary acrylic sheet and ABS composite board. The latter two materials with themselves some flaws, in fact, they are not suitable for making bathtubs.

Acrylic, the chemical name as methyl methacrylate, is dedicated for sanitary acrylic sheets with excellent surface finish, and its ware resistance is equivalent to aluminum and easily cleaning. If surface scratch occurs accidentally, it could be removed quickly by the polishing agents. As the acrylic sheet has flexibility, it is not easy to crack even the surface collision. In addition, special sanitary acrylic sheet has a strong corrosion resistance and light transmission, because the pigments can be integrated into the sheet steadily, therefore, its color is very stable, it is not easily fade under sunshine and rain. Therefore, special sanitary acrylic sheet is widely used for indoor and outdoor decoration, especially producing high quality acrylic bathtubs.

Ordinary acrylic sheet is low hardness, poor heat resistance, less extended, easily crack fragile and deformed, also the color is instability, it can be fuzzy during producing. After shaped, because the bottom is generally stretched widely, the color uneven happens.At the corner of the bottom, you could see white, yellow and other discoloration etc.

The ABS acrylic composite sheet is made of ABS adhesive acrylic on both sides. Thus it is easily observed at the cutting edge. As the ABS acrylic composite sheets are two different materials bonded together, resulting in the shrinkage rate is inconsistent; it becomes delamination for long term changes under hot and cold temperature. Furthermore, there is only very thin acrylic covered on the ABS sheet, it is stability and were resistance is very poor. While shaped under the mold, it can be white or other discoloration.

In order to ensure top quality acrylic bathtub to all of our clients, GreenGoods only use high quality and special sanitary acrylic sheet to produce our acrylic bathtub. You will have no worries to import acrylic bathtub from us even you buy them for your star hotel projects or civil projects.
