LONGSUN LSP336 Ceramifiable Polyolefin
LONGSUN LSP336 Ceramifiable Polyolefin is a functional modified polymer material. Its core feature is that it possesses the flexibility and processability of polyolefins at room temperature, while rapidly converting into an inorganic ceramic-like substance when burned or incinerated at high temperatures, thereby achieving fire resistance, heat insulation, and shape retention effects.
I. Core Properties: Key Differences from Ordinary Polyolefins
1. High-Temperature Ceramification Performance
When exposed to flames or high temperatures, the material undergoes reactions such as melting, cross-linking, and curing, forming a continuous and dense ceramic body within a few minutes. This ceramic body can withstand high temperatures ranging from 800℃ to 1300℃, without melting or dripping, effectively preventing the spread of heat and flames.
2. Flexibility and Processability at Room Temperature
When not exposed to high temperatures, it maintains the soft texture of polyolefins and can be processed like ordinary plastics through extrusion, injection molding, blow molding, and other processes. It can be made into various forms such as wires, cables, pipes, and sheets, solving the problems of high brittleness and poor processability of traditional ceramic materials.
3. Excellent Flame Retardancy
It achieves flame retardancy through its own ceramification reaction without relying on large amounts of halogenated flame retardants. During combustion, it has low smoke density and minimal release of toxic gases, complying with environmental flame retardant standards (e.g., ROHS, UL94 V-0 rating).
4. Good Insulation Performance
At room temperature, its insulation performance is equivalent to that of ordinary polyolefins; after converting into a ceramic body at high temperatures, it still maintains a certain level of electrical insulation. It is suitable for fire-resistant and insulating scenarios in the electrical field.
II. Main Application Fields: Focus on Scenarios with "Fire Resistance + Functional" Requirements
Its properties determine that it is mainly used in fields with clear requirements for fire resistance, heat insulation, and insulation, especially in scenarios that need to balance processability at room temperature.
1. Electrical and Electronic Field
As a core application scenario, it is used in the insulation layer or sheath of wires and cables (especially fire-fighting cables, rail transit cables, and new energy vehicle wire harnesses). In case of fire, it can maintain line insulation, buying time for emergency power supply and signal transmission. It can also be used in fire-resistant isolation layers inside electrical appliances and connector housings.
2. Construction and Building Materials Field
It is used as a fire-resistant sealing material in buildings (e.g., sealing cable penetration holes and pipeline gaps). During fire, it expands and ceramifies to seal gaps, preventing the spread of flames and toxic gases. It can also be made into fire-resistant panels and sealing strips for fire-resistant doors and windows.
3. Transportation Field
In addition to new energy vehicle wire harnesses, it is used in fire-resistant internal components of high-speed trains and aircraft (e.g., pipeline protective sleeves and in-cabin partitions), meeting the strict fire resistance standards of transportation vehicles.
4. New Energy Field
It is applied in fire-resistant isolation films for lithium battery packs and cable protection in photovoltaic power stations, addressing the high-temperature and fire safety requirements of new energy equipment.
