Latest company case about Shenzhen Hanast New Material co.,LTD Certifications

This case study describes how a decorative wall-panel producer serving buyers across Russia and Central Asia improved its gypsum cultural stone line by adopting HN-E Series platinum-cure (addition-cure) liquid silicone rubber from Shenzhen Hanast New Materials. The result is sharper texture, more repeatable dimensions, and longer mould life for high-volume gypsum casting.

Gypsum cultural stone—3D wall panels, split-face brick, slate and rock reliefs—must reproduce fine surface detail while keeping every tile identical. The producer faced four recurring problems:

• Loss of fine detail in the natural stone texture after repeated casting;
• Mould shrinkage that gradually changed panel dimensions;
• Early mould failure under continuous high-volume runs;
• The need for a safe, odourless material inside the workshop.

HN-E is a translucent, two-component platinum-catalysed liquid silicone rubber. Components A and B are mixed 1:1 by weight and cure at room temperature or with heat acceleration, offering eleven hardness grades (Shore A 0–60) so the ideal grade can be matched to each product.

For gypsum wall panels the producer selected HN-E625–E640, balancing flexibility for detail capture with enough firmness for stable panels.

1. Pre-mix Components A and B until homogeneous.
2. Weigh A and B in an accurate 1:1 ratio on a precision scale.
3. Mix for 2–3 minutes, scraping the walls and bottom.
4. Degas under vacuum to remove entrapped air.
5. Pour into the clean, dry master frame within the 30–40 min pot life.
6. Cure 3–4 h at room temperature, or 80–100°C for ≤20 min, then demould.

• Natural stone texture reproduced with 1:1 sharpness in gypsum panels;
• Shrinkage ≤0.1% kept panel dimensions identical across long production runs;
• High tensile and tear strength extended mould service life;
• Odourless, non-toxic material improved workshop conditions;
• Room-temperature cure simplified hand pouring, while heat cure supported faster output.

For gypsum cultural stone producers targeting Russia and Central Asia, HN-E platinum-cure liquid silicone rubber delivers higher-quality panels, lower mould-replacement cost, and a safer production floor.
