Acrylic plate

Acrylic plate(Akuriruban)acrylic resinBoard made of[1][2]..It is similar to a glass plate in that it is a highly transparent plate, but its use is different.Aquariums, especially large aquariums, are made of acrylic plates because they are transparent enough to withstand water pressure.On the other hand, it is not used as a substitute for window glass (outside the building) due to its poor heat resistance.


High transparency[1][3]..The light transmittance of the acrylic plate is 93%, and the light transmittance is 92%.ガ ラ スSurpass[1][3][4][5].

Easy to cut, drill, bend, chamfer, polish, etc.[1][3]..You can also engrave and print.[4].

Strong, hard to break, debris does not scatter even if broken[3][5][6]..Excellent impact resistance[1]..Surface hardness is similar to aluminum[7].

Excellent weather resistance[1]..Durable[3]..Extremely low decrease in transparency and strength[5].

If it is a shallow scratch, it can be refinished with an abrasive.[7].

Easy to be charged with static electricity and easy to get dust[7].


Extruded board

Acrylic board made by extruding clay-like melted acrylic resin with a roller[3][8]..The thickness of the board can be made up to 20 mm[3]..The thickness of the board is constant[4]..Cheaper than cast board[2][4][5][8].

Coarse molecular weight[4], The molecular weight of the extruded plate is 1/15 of the cell cast plate[7]..Easy to stick when cut[4]..Therefore, it is suitable for use as a board.[4]..In addition, the heated part is easy to melt and is not suitable for high-speed cutting.[8].

Easily soluble in solvents[8][7]..Suitable for solvent bonding[3][8][7]..Easy to bend by applying heat[3].

Sensitive to chemicals[4]..Cracks with solvents and chemicals[Note 1]Is likely to occur[8].

Lack of durability[2]..Sensitive to changes in temperature and environment[3]..Sensitive to heat[3], Thermal deformation temperature is low and softens early[7]..Easy to crack[3]..Fine cracks may occur on the surface depending on the type of solvent.[7].

Cast board

Acrylic plate made by stacking two upper and lower glasses, pouring acrylic raw material between them and curing[3][8]..Higher hardness than extruded material[3][4][8], Hard to warp[3][8]Suitable for machining[4][5],expensive[2][4][5][8]There are features such as.It is also possible to make a large board.[2]..Due to the manufacturing method, there are variations in the thickness of the board.[4][8]..Acrylic color boards are mostly cast boards[4].

Fine molecular weight[4]..Therefore, it is difficult to dissolve in a solvent when adhering.[4][8]..Solvent adhesion process takes time and adhesion is weak[3], Also low strength[8]..Suitable for high speed cutting[8].

FX board

A type of cast board[5]..Fewer binding molecules than regular cast boards[5]..Therefore, processing such as solvent bonding, polishing, cutting, and drilling is easy.[5]..Suitable for solvent bonding[5].

Less deterioration over time like extruded plates[5].
