Hi there,​
If you have checked our inbox recently, you may have noticed a few "is the price going up?" messages popping in. Fair question. Let us be straight with you.

What is happening

  Through September 2026, domestic PMMA (acrylic) resin prices in China have climbed sharply. Market spot quotes for general-purpose extrusion and casting-grade resin moved up by roughly RMB 2,000 per tonne month-on-month, landing in the RMB 14,000–16,200 per tonne range by late September. Optical-grade and high-impact grades sit at the top of that band.
  This is not a small blip, and we are not going to pretend it is business as usual.

Why it is happening
Two forces are pulling costs upward at the same time:
1·MMA monomer cost push. The upstream methyl methacrylate (MMA) monomer that we polymerize into acrylic sheet has been rising on stronger acetone and methanol costs, plus firmer crude oil. East China MMA spot prices topped RMB 13,300 per tonne in September.
2·Tighter short-term supply. A major domestic PMMA line under Sinopec Zhejiang went into a planned turnaround this month, and several other plants cut operating rates. Industry-wide utilization slipped to around 53%, and producers have been holding volumes back rather than flooding the market.
In short: the resin market is in a cost-driven, short-term squeeze — not a permanent capacity shortage, but enough to move the needle right now.

What this means for our small factory
  We are a workshop-scale acrylic sheet maker based in Quzhou, not a listed conglomerate. When resin moves RMB 2,000 per tonne, that does not sit quietly on our balance sheet. Our casting and extrusion lines feel it within days.
  What it does not change: our quality standard, our tolerance for yellowing or inconsistent thickness, or our willingness to run small trial orders for customers who are still testing a new design.

Our commitment to you
1.Transparent pricing. If an order needs a price adjustment, we will tell you why, and we will show you the resin benchmark we are buying against.
2.Steady supply. We have locked in a reasonable resin cushion for the next 4–6 weeks so planned shipments are not caught off guard.
3.Quality unchanged. Same casting and extrusion specs, same tolerance, same batch inspection — we will not quietly substitute cheaper resin.
4. Flexible small orders. As a small plant, our sweet spot is still prototype runs, trial batches and repeat reorders, not bulk stockpiling. We will work with your actual demand rhythm.

A small piece of advice
  If you are holding a project that needs acrylic sheet in October or November, now is a reasonable time to confirm the spec and place a trial order — not because we are pushing panic buying, but so we can reserve line capacity for you before the next maintenance cycle. If your timeline is flexible, waiting through October may reveal a calmer market as some of those turnaround lines come back online.
  We are a small factory, and small factories survive by being straight with the people who buy from them. If you have a quote on your desk that feels off, send it over and we will walk you through it.
