Bathtub liners also known as tub liners, acrylic tub liners and tub inserts are made by vacuum forming an acrylic or PVC (poly vinyl chloride) sheet which is heated then formed in a mold by applying vacuum. Having the proper mold is important for the tub liner to fit properly. Typically a bathtub liner will fall between the cost of replacing a bathtub at the high end and bathtub refinishing at the lower end in cost when renovating a damaged or outdated bathtub.
100% ABS Acrylonitrile Butadiene Styrene is nearly indestructible. Disadvantages: it doesn't manage as well with UV light, possesses lower optical clearness and possesses a lower sheen when compared with acrylic, it is susceptible to dampness penetration and is normally not used by sanitary goods. ABS is less expensive than acrylic.
Disadvantages: acrylic plastics can be expensive but are not as sturdy as ABS. Acrylics are more brittle than ABS and susceptible to cracking.
Disadvantages: Of using PVC Vinyl, composition is softer, lower in gloss and more susceptible to being damaged or scratched, thou it is the lowest cost solution.
Best Solution: Bath tub liners produced from a blend composite provides the best solution in strength, durability and hygiene – is usually a blend laminate whereas 85% ABS Acrylonitrile Butadiene Styrene, used as the foundation and provides dimensional stability and then layered with 15% acrylic for a sanitary, sturdy and aesthetic appeal. Spend will be close to 10% more regarding the cost of ABS capped acrylic laminate polymer over bath tub liners made from PVC. Tub-liners manufactured of acrylic capped ABS specifically for sanitary applications, providing superior scratch resistance, good impact performance and dimensional stability. Benefits and features of bathtub liners made from acrylic capped ABS for bath tub liner installation are:
- High scratch resistance,
- Beautiful surface aesthetics with high gloss,
- Excellent impact resistance,
- Highly modulus/stiffness,
- Excellent resistance to bath room cleaning chemicals.
- Easily cleaned,
- Has good molding characteristics,
- UV resistance, won’t yellow over time.
- Highly dimensionally stable, so it won’t deform over time.
Bath tub liner thickness: the majority of bath tub liners manufactured are .250 1/4 inch or thinner.
The thickest ABS acrylic capped bathtub liner material is .280” thick for shallow bathtubs and .325” for extra deep bath tubs. This provides additional stability from flexing.
