Langfang Dihong Energy Saving Technology Co.,Ltd.
Your Trusted Partner for High-Performance Insulation Solutions
Welcome to Langfang Dihong Energy Saving Technology Co.,Ltd.,a leading Chinese manufacturer specializing in advanced thermal insulation materials for global markets.Headquartered in Langfang,Hebei Province–a strategic industrial hub in Northern China–we are dedicated to providing energy-efficient,safe,and reliable insulation solutions for building construction,HVAC&R systems,and industrial applications worldwide.
Core Products:Engineered for Excellence
We focus on manufacturing premium insulation materials renowned for their superior performance:
Phenolic Insulation Boards(PF Boards):
Unmatched Fire Safety:Achieves premium fire ratings(typically Class A/Class 0 equivalent to international standards like ASTM E84,BS 476).The ideal choice for high-rise buildings,public facilities,and applications demanding stringent fire safety.
Exceptional Thermal Efficiency:Extremely low thermal conductivity minimizes heat loss/gain,significantly enhancing building and system energy efficiency.
Low Smoke&Toxicity:Generates minimal smoke and low toxicity fumes when exposed to fire,enhancing life safety.
Dimensional Stability&Durability:High compressive strength,excellent resistance to shrinking,warping,and harsh environmental conditions.
Rubber Foam Insulation(NBR/PVC Foam):
Superior Flexibility&Ease of Installation:Soft,elastic closed-cell structure allows for easy cutting and seamless fitting around pipes,ducts,and complex geometries,ensuring excellent vapor seal.
High Thermal Performance&Condensation Control:Very low thermal conductivity effectively prevents energy loss and surface condensation.
Outstanding Moisture Resistance:Exceptional resistance to water vapor transmission maintains long-term insulating performance.
Environmentally Durable:Resistant to ozone,weathering,and aging.Available in eco-friendly formulations.
Phenolic Insulation Pipe Sections(PF Pipe Sections):
Precision Fit for Pipes:Pre-formed cylindrical sections ensure quick,easy installation and continuous thermal protection for pipes,eliminating thermal bridging.
Inherent Fire Safety:Inherits the superior fire performance of phenolic foam(Class A/Class 0),critical for HVAC,industrial piping,and fire-sensitive areas.
Optimal Energy Saving&Anti-Condensation:Provides excellent thermal insulation to prevent energy waste and pipe sweating.
Chemical Resistance&Robustness:Suitable for demanding industrial environments.
