Outdoor Roller Blinds

PVC foam coating is prone to blocking (coating layers sticking together) or cracking (coating becoming brittle and peeling) after long-term storage. This is a well-known pain point of the classic PVC foam process. The severity varies by supplier formulation and storage conditions. It is recommended to avoid long-term storage of PVC foam coating products, or choose more storage-resistant alternatives such as acrylic coating.

The typical structure of sunscreen blackout fabric is: face layer of regular sunscreen fabric (70% PVC + 30% polyester), middle layer of TPU film lamination, and back layer of acrylic coating. When ordering, confirm: face layer PVC/polyester ratio, back color, and total fabric weight (face + TPU film + coating, with ±5% tolerance being a common industry acceptable range). The TPU film does not require separate parameter confirmation — only confirm that actual light-blocking performance matches the buyer's provided sample.

For bedrooms where total darkness matters, blackout roller blinds or blackout honeycomb shades are the top choices. Zebra blinds offer adjustable light control but cannot achieve full darkness. Honeycomb shades add the best thermal insulation, which helps reduce energy costs in both winter and summer.

Traditional PVC/PS faux wood venetian blinds use lead-based heat stabilisers. Since 29 November 2024, the EU has fully prohibited PVC articles with lead concentration ≥ 0.1% by weight (REACH Annex XVII, Entry 63). Suppliers must switch to calcium-zinc stabilisers. Additionally, the phthalate restriction (≤ 0.1% combined for DEHP/DBP/BBP/DIBP) applies equally to PVC plasticisers in these products.
