UNDERWATER GRADE KOAGLAS
UNDERWATER GRADE KOAGLAS® is monolithically cast polymethyl methacrylate (PMMA) acrylic manufactured by the SAFETY STANDARD FOR PRESSURE VESSELS FOR HUMAN OCCUPANCY (PVHO-1)
UNDERWATER GRADE KOAGLAS® is closely watched and monitored for 24 hours a day from the production start to the finish of annealing process for relieving residual stress. So it provides high molecular weight, outstanding physical, chemical and optical properties. In addition, it can be bent easily so that it could be used aquarium tunnel section, cylindrical and various shape of aquarium window without changing its properties.
Certified and guaranteed UNDERWATER GRADE KOAGLAS® offers
1. Clear with minimum haze (>92% total transmission)
2. Greater tensile strength offer over 13.5 safety factor
- Acrylics for water retaining applications are designed to tensile stress level
of 800 psi
- Average tensile strength of Underwater Grade KOAGLAS® is 10,800 psi
3. 30 years guarantee against yellowing
4. > 1.6 residual Monomer guarantee less internal material tensions
STANDARD SIZE OF underwater grade koaglas
KOATECH's bonding adhesive have a tensile strength over 9000 psi at the bond offers to make limitless sizes and various shapes.
Our endless efforts to develop technologies enable us to cope with any requests from our client.
Now KOAGLAS is being used from military, medical and scientific use and also used as an important engineering plastic to make mock-up model.
