The Indian textile industry is undergoing a significant transformation as manufacturers increasingly adopt Poly Methyl Hydrogen Silicone (PMHS) technology to produce high-performance waterproof fabrics. This shift represents a strategic response to growing market demand for functional textiles that combine water resistance with breathability, durability, and environmental sustainability. The adoption of PMHS-based waterproofing solutions is positioning Indian textile mills at the forefront of technical textile innovation, enabling them to compete effectively in both domestic and international markets.
India’s waterproof textiles market has demonstrated robust growth, reaching USD 89.42 million in 2024 and projected to expand to USD 156.03 million by 2033, achieving a compound annual growth rate (CAGR) of 5.91%. This growth trajectory is fueled by several key factors, including the expansion of outdoor recreational activities such as trekking, camping, and adventure sports, which drive demand for waterproof apparel and gear. Additionally, rising consumer awareness about the practicality of weather-resistant clothing in urban environments has created new market segments beyond traditional rainwear applications.
The global waterproof fabrics market presents even more substantial opportunities, with projections indicating growth from USD 2.5 billion in 2025 to USD 4.7 billion by 2035, at a CAGR of 6.5%. Clothing applications dominate this market, accounting for 42.6% of revenue share, while breathable waterproof fabrics capture 57.3% of market share due to their superior comfort and performance characteristics.
Poly Methyl Hydrogen Silicone (PMHS), also known as Methyl Hydrogen Silicone Fluid, represents a breakthrough in waterproofing technology for textiles. This chemical compound (CAS No. 63148-57-2) contains active Si-H bonds in its molecular structure, enabling it to participate in various chemical reactions and cross-link under the influence of metal salt catalysts at low temperatures.
The most significant advantage of PMHS lies in its exceptional waterproof performance. When applied to fabric surfaces, it forms a durable hydrophobic film that provides excellent water repellency while maintaining moderate softness. Unlike traditional waterproofing agents, PMHS exhibits minimal changes in physical properties across a wide temperature range, making it suitable for diverse climatic conditions. The technology is thermally stable at temperatures up to 150°C for extended periods, ensuring long-term performance durability.
PMHS-based waterproofing solutions offer several key benefits for textile applications:
Superior Water Repellency: The technology creates a permanent hydrophobic barrier that prevents water penetration while allowing vapor transmission, addressing the critical need for breathability in waterproof garments.
Enhanced Durability: Fabrics treated with PMHS demonstrate excellent resistance to abrasion, maintaining their waterproof properties through multiple wash cycles and extended use.
Environmental Compatibility: PMHS is non-toxic, non-dangerous, and compatible with most plastics and surface coatings, making it suitable for a wide range of textile substrates including natural and synthetic fibers.
Indian textile mills are integrating PMHS technology through advanced coating and finishing processes. The manufacturing workflow typically involves several key stages:
Fabric Preparation: Gray cloth selection and thorough cleaning to remove impurities that could interfere with coating adhesion.
Surface Treatment: Plasma dust removal and surface activation to enhance PMHS bonding with fabric fibers.
Coating Application: Uniform application of PMHS-based waterproofing formulations using precision coating equipment.
Curing Process: Cross-linking under controlled temperature conditions using metal salt catalysts to form the permanent waterproof film.
Quality Control: Rigorous testing for hydrostatic pressure resistance, breathability, and durability to ensure compliance with international standards.
The adoption of PMHS technology by Indian textile mills is supported by compliance with global waterproofing standards that validate product performance and quality. Key certifications include:
ISO 811: International standard for water pressure resistance measurement, with materials rated above 1,000 mm considered waterproof.
EN 343: European standard for waterproof and breathable protective clothing, classifying garments on both water penetration resistance (Classes 1-4) and water vapor resistance/breathability (Classes 1-4).
AATCC 127: North American standard for hydrostatic pressure testing before leakage.
OEKO-TEX Standard 100: Certification for chemical safety and environmental compliance.
These certifications provide Indian manufacturers with market access to international buyers who demand verified performance and quality assurance.
PMHS-treated waterproof fabrics find applications across multiple market segments:
Outdoor and Sportswear: Jackets, trousers, and accessories for hiking, mountaineering, and adventure sports, where breathable waterproof protection is essential.
Workwear and Protective Clothing: Industrial garments for construction, transportation, and emergency services that require reliable weather protection.
Technical Textiles: Tarpaulins, tents, and covers for automotive and industrial applications.
Lifestyle Apparel: Urban outerwear and fashion garments that combine style with functional weather protection.
The shift toward PMHS technology aligns with the industry’s growing emphasis on sustainability. PMHS-based waterproofing offers several environmental advantages:
Reduced Chemical Footprint: Compared to traditional fluorinated DWR (Durable Water Repellent) coatings that contain PFAS (“forever chemicals”), PMHS provides effective waterproofing with lower environmental impact.
Energy Efficiency: The low-temperature curing process of PMHS reduces energy consumption during manufacturing.
Longevity: Durable waterproof performance extends garment lifespan, reducing textile waste and supporting circular economy principles.
The waterproof fabrics market features several global players, including Gore (USA/Germany), Sympatex (Germany), and Ventile (Switzerland/UK), who have established strong positions with advanced membrane technologies. Indian textile mills adopting PMHS technology are positioning themselves to compete in this dynamic market by offering cost-effective alternatives with comparable performance characteristics.
