Sisal Fiber 90~130CM for Spinning / Plaster / Gypsum / Building Material

Sisal fiber measuring 90 to 130 cm is a high-grade, multi-purpose raw material widely used for industrial spinning, building reinforcement, and acoustic plaster moldings. Extracted from the leaves of the agave plant (Agave sisalana) through a process called decortication, it provides high mechanical tensile strength and flexibility. It is a highly sustainable, biodegradable alternative to synthetic reinforcement fibers. [

Here is an overview of its core specifications, industrial applications, and how to source it.

Technical Specifications & Grading

Industrial-grade sisal fiber bundles generally feature the following quality metrics:

• Length: 90 cm to 130 cm (Ideal for uniform spinning and high-load reinforcement).
• Common Grades: UG (Under Grade) or SSUG (Special Under Grade) Grade A / Type 1.
• Color: Premium natural cream-white to soft yellowish-brown.
• Moisture Content: Formulated to 10%–14% to prevent mildew while retaining fiber elasticity.
• Impurity Rate: Strict limit of ≤ 2%–3% dust and pulp fragments to ensure clean binding.
• Packaging: Compressed industrial bales weighing between 100 kg to 250 kg.
