Product Overview

PMMA LED Diffusers Overview

PMMA, also called acrylic, is chosen where clarity, surface hardness and long-term colour stability come first. Acrylic diffusers keep their transmission and resist yellowing better than most alternatives, which is why they are widely used in architectural and commercial interiors. We extrude PMMA in clear, opal and frosted grades and can co-extrude a diffusing layer over a clear body.

Manufacturing Process

From drawing to packed profile

1

Drawing

2D drawing, 3D file, sketch or an existing sample.

2

Material

PC or PMMA, single-colour or two-colour, selected for optics, impact and UV stability.

3

Tooling

In-house die design and die manufacturing.

4

Extrusion

Trial run and parameter setting on a matched extrusion line.

5

Cutting

Cut to length, mitring, notching, drilling and CNC machining.

6

Inspection

Dimensional, appearance and optical checks against the approved sample.

7

Packaging

Protective film, sleeving, cartons and pallets to your requirement.

Quality Control

How the profile is checked

Every profile is produced against an approved sample or drawing. We check incoming resin, approve the first piece, measure the profile during the run, and carry out a final appearance and dimensional inspection before packing. Optical grades are verified for transmission and diffusion consistency.
  • Incoming resin inspection and batch traceability
  • First-piece approval against the approved sample or drawing
  • In-process dimensional checks on profile width, height and wall thickness
  • Light transmission and haze measurement on optical grades
  • Appearance inspection under standard lighting conditions
  • Final random inspection before packing and palletising

FAQ

Frequently Asked Questions

They are the same material. PMMA is polymethyl methacrylate; acrylic is the common trade name.
PMMA has very good UV stability and low yellowing compared with many transparent polymers, which is why it is used for long-life architectural work.
Yes. Co-extrusion or surface texturing can be applied to selected faces of the profile.
