Working with Extruded Acrylic Sheet

Is Extruded Acrylic Sheet easy to machine?

Use sharp single-flute or O-flute cutters at high spindle speed and low feed with air cooling to prevent melting and re-welding of chips; drill with 0° rake acrylic-point drills to stop grab and edge break-out. Anneal at 80 °C for 1–2 h per mm of thickness after machining to release stress.

Can Extruded Acrylic Sheet be welded?

Solvent cementing with dichloromethane/chloroform-type cements or acrylic adhesives (UV-cure or two-part) is the first choice; extruded sheet cements quickly but crazes more easily than cast. Hot-gas and ultrasonic welding are possible, but do not load a fusion-welded joint immediately.

Can Extruded Acrylic Sheet be formed, bent or molded?

Thermoforming window is 150–175 °C after pre-drying 2–4 h at 70–80 °C. Extruded sheet reproduces mould detail well and forms at lower temperature than cast, but shrinkage is anisotropic — longitudinal (extrusion-direction) shrinkage is clearly greater than transverse.

Limits by weight percent from the governing specification, written the way the spec states them — a single maximum for impurities, a range for alloying elements, and the base element as balance. Nominal is the typical mid-range value.

What surface finishes work on Extruded Acrylic Sheet?

Edges can be flame-polished (fast, but it raises internal stress and cracking risk, so anneal afterwards) or sanded and buffed with polishing compound. The sheet accepts screen printing, UV printing, vacuum aluminising and film lamination; do not wipe repeatedly with ammonia- or alcohol-based cleaners.

Extruded Acrylic Sheet — frequently asked

What is Extruded Acrylic Sheet used for?

Extruded Acrylic Sheet is typically used for thermoformed light covers, retail fixtures, vacuum-formed parts and glazing panels. In short: lowest-cost acrylic sheet; tightest thickness tolerance; easiest thermoforming acrylic.

What is the yield strength of Extruded Acrylic Sheet?

Extruded Acrylic Sheet has a typical yield strength of 66 MPa (9.57 ksi) and a tensile strength of 68 MPa (9.86 ksi) — stronger than 76% of polymer grades. Strength varies by condition: see the 6 listed tempers.

Is Extruded Acrylic Sheet easy to machine?

Reasonably — machinability is rated good (65/100, better than 66% of polymer grades). Use sharp single-flute or O-flute cutters at high spindle speed and low feed with air cooling to prevent melting and re-welding of chips; drill with 0° rake acrylic-point drills to stop grab and edge break-out. Anneal at 80 °C for 1–2 h per mm of thickness after machining to release stress.

Yes — weldability is rated very good (70/100). Solvent cementing with dichloromethane/chloroform-type cements or acrylic adhesives (UV-cure or two-part) is the first choice; extruded sheet cements quickly but crazes more easily than cast. Hot-gas and ultrasonic welding are possible, but do not load a fusion-welded joint immediately.

What is the maximum service temperature of Extruded Acrylic Sheet?

Extruded Acrylic Sheet is rated for continuous use to about 72°C (162 °F), and briefly to 90°C. Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
