About ACRYHOLZ

ACRYHOLZ is a German manufacturer of stabilized wood based in Berlin. The company stabilizes wood through deep-penetrating impregnation with a proprietary acrylic resin system (PMMA) using the puq process, and from it produces handle materials such as handle blocks and handle scales. The wood species processed are predominantly native to Europe, including poplar, beech, birch, maple, ash, ash maple, walnut, chestnut, elm, lime, thuja, plane, myrtle and bog oak. In addition to direct sales via its own shop, ACRYHOLZ offers contract stabilization of customer wood from 13 liters volume with a lead time of around five working days. The coloring techniques include single-color, two- and three-color, and transparent variants. Stabilized wood from ACRYHOLZ is used in knife making, woodturning, instrument making, jewelry and design, furniture and interior fittings, arts and crafts, sporting bow making, and writing instruments, and can be sanded, sawn, drilled, milled, turned, and polished like hardwood.

Materials and Processes

PUQ

Wood stabilization using the puq process

Deep-penetrating impregnation of wood with the proprietary acrylic resin system for greater dimensional stability, hardness, and moisture resistance.

PMMA

PMMA (acrylic resin/polymethyl methacrylate)

Proprietary, specially developed resin system based on high-quality raw materials and carefully selected colorants.

PAPPEL

Poplar (burl)

Frequently used native wood species for handle blocks, handle scales, and turning wood.

BUCH

Beech (flamed)

Flamed beech for stabilized handle blocks in knife making.

ESCHAH

Ash maple (burl)

Burl wood for handle blocks and handle scale pairs.

MISC

Other European wood species (birch, maple, ash, walnut, chestnut, elm,

Broad spectrum of native and European wood species as an alternative to tropical hardwoods.
