Acrylic Coated Fiberglass Sleeves Manufacturer in India
Being an established supplier of certified, tested class F insulation sleeving for motors, appliances and general electrical apparatus in India, we at Harnawa Inc., being an established acrylic coated fiberglass sleeve manufacturer in India, cater to the needs of our customers in the form of pan-India deliveries from our Mumbai base and international certifications.
Why Acrylic Coating Is the Right Choice for Everyday Electrical Insulation
All applications of the insulation do not require high-temperature resistance. In the case of the majority of motors, devices, meters, and other types of electrical machinery, the most important thing about insulation would be its ability to provide good insulation up to 155°C as Class F Insulation, ease of use during installation, and overall high efficiency without paying extra for high-temperature resistant coatings which are not required in your particular case. This is when acrylic-coated fiberglass sleeve becomes really useful.
What the Acrylic Resin Coating Actually Does
The modified acrylic resin insulating paint coating isn’t just a surface finish — it fundamentally changes how the braided fiberglass performs in service:
- Provides Flexibility & Elasticity — Ensures that the sleeve can be fitted easily on bends, terminals, and non-linear wire layout without breaking
- Increases Fraying Resistance — Holds the braided fiberglass construction together, and prevents any fraying
- Increases Smoothness — Helps the sleeve slip easily onto the wires, making for easy assembly line work
- Increases Strength & Stability — The carefully regulated heating and drying process used while manufacturing the sleeve ensures that the coating is securely attached to the braided fiberglass structure
Alkali-Free Fiberglass — Why the Base Material Matters
The fiberglass core is explicitly alkali-free, and this fact proves more important than one would expect. Indeed, alkali-free glass fiber provides better electrical insulation characteristics and greater moisture resistance as compared to regular glass fiber, which leads to insulation resistance equal to or exceeding 1.0 × 10⁹ Ω of the sleeve, which value is rather important when comparing this material with a technical datasheet.
Where Acrylic Coated Sleeve Fits vs. Other Fiberglass Sleeve Options
Harnawa Inc. supplies fiberglass sleeving across multiple coating types, each suited to a different balance of temperature rating, flexibility, and cost:
| Sleeve Type |
Insulation Class |
Best Suited For |
| Acrylic Coated Fiberglass Sleeve |
Class F (155°C) |
General electrical equipment, appliances, motors — cost-effective everyday insulation |
| Varnished Fiberglass Sleeving |
Class B |
Moderate temperature and voltage applications |
| PU Coated Fiberglass Sleeves |
Class F (155°C) |
Enhanced mechanical strength alongside Class F insulation |
| Silicone Coated Fiberglass Sleeves |
Class H |
Higher-temperature applications requiring extended thermal margin |
Summary point: If your application works within the normal Class F temperature range and does not need the mechanical strength of PU coating or the heat-resistance property of silicone coating, then an acrylic coated fiberglass sleeve will perform adequately at a lower cost.
Applications of Acrylic Coated Fiberglass Sleeve
This sleeve is widely specified across:
- Motors & Generators – Insulation of winding leads and general electrical wiring
- Transformers – Component and connector insulation
- Electrical Appliances – Wiring of domestic and commercial appliances
- Meters & Radios – Electronic device wiring insulation
- Cable Harnesses – General purpose insulation in cable harness manufacture
- General Electrical Equipment – Wherever flexible, high-reliability Class F insulation is required
RoHS Compliance & Custom Color Options
To the manufacturers faced with environmentally conscious procurement needs, the RoHS compliance of this sleeve makes it easy to specify without any further worries about compliance. This is made even easier by the fact that you can choose from several colors (Natural, Red, Black, Grey and others).
Completing the Insulation System
Acrylic coated fiberglass sleeve is frequently used alongside other insulation materials to build a complete electrical protection system:
Sourcing all of these materials from a single certified supplier ensures compatibility, consistent quality standards, and simplified procurement for OEMs and equipment manufacturers.
