Products Hegeler & Söhne is a supplier of the fibre-cement industry since 1960 and in 1981 we started selling PVA-fibre to the industry for reinforcement of fibre-cement sheets, and we accompanied our customers since then in their conversion from asbestos containing to non-asbestos production. Since 1994 we offer PVA-fibre of first class standard from China. It is sold and used in those markets where asbestos has been or will be banned. |  | | | | | We highly recommend the following PVA-fibres from our portfolio: PVA-fibre HPF Top-grade fibre, comparable to Japanese PVA-fibre grades of premium standard PVA-fibre STM Well introduced, most-sold standard-fibre of high quality level T a b l e o f C h i n e s e P V A - f i b r e g r a d e s S t a n d a r d | Grades | Unit | HPF | STM | | Titre | dtex | 2,0 +/- 0,25 | 2,0 +/- 0,25 | | Tenacity | cN/dtex | ≥ 12,80 | ≥ 11,40 | | Young's Modulus | cN/dtex | ≥ 290 | 280 +/- 20 | | Extension at Break | % | ≤ 7,00 | ≤ 7,50 | | Cut Length | mm | 5 or 6 | 5 or 6 | | Dispersability class | 6 classes | 1 + 2 | 1 + 2 | | Moisture Regain | % | 5 | 5 | | Hot Water Solubility | % | ≤ 2,00 | ≤ 2,00 | | Sizing Agent | % | 0,25 +/- 0,15 | 0,25 +/- 0,15 | | Specific Gravity | | 1,29 | 1,29 |
