Solid surface was introduced to the market by the company Dupont under the name Corian in 1967.

It is solid, non-porous, homogeneous surface material consisting of circa 70% aluminium trihydrate obtained from bauxite
and circa 30% acrylic resin called also as polymethylmetacrylate or PMMA. In English it is called „solid surface“
or less precisely „SolidStone“
(trademarks of various manufacturers are e.g. Corian, Getacore, Hanex, Hi-Macs, Kerrock, Krion, Staron, etc.).

In much rare cases polyester resin is used as binder (Avonite, Polystone).

Distribution of raw slabs and also fabrication of worktops and other products from solid surface is provided by sister company MosaicSolid, based also in Svojanov.

Main physical parameters

Bulk density

1.7 g/cm³

Hardness

2-3 according to Mohs

Flexural strength

57-74 MPa

Abrasiveness

about 60 mm3/100 rev. acc. to DIN ISO 4586 T6

Volume absorption

0.6 %

Heat resistance

100-110°C Iron pad for putting the hot objects away is necessary

Chemical resistance

product will be damaged by action of HNO 3, HCl, CH 2Cl 2

Ecological parameters

meets the 51 NSF/ANSI Standard for contact of the material with foodstuffs, thanks to quite closed surface it does not support the bacteria growth. It meets standard GreenGuard Indoor Air Quality Certificate


Advantages and disadvantages by usage as surface material

Advantages:

  • Non visible joints on longer products (jointless technology)

  • 100% colour consistency

  • Surface is repairable

  • Rounded edges possible, the sinks can be made from the same material as the worktop (thermoforming)

  • Translucent effect by some colours, possibility to insert LED diodes

  • Resistant to microorganisms

  • Warm on touch

Disadvantages:

  • Low hardness and higher absorption

  • Sufficient chemical resistance

  • Lower heat resistance
