PE sulfur & chlorine aging-resistant masterbatchPE SULFUR & CHLORINE AGING-RESISTANT MASTERBATCH
The hot, humid environment of sulfur fumigation easily causes ordinary PE agricultural film to suffer acidic aging, deformation, yellowing and breakage; chlorine ions volatilised from irrigation water keep corroding and accelerate failure. M88 passivates and resists sulfur fumigation products and chloride attack, protecting the film’s physical and mechanical strength and extending its service life.

Sulfur fumigation chamber: without M88 yellowed and brittle vs with M88 intact
Toggle the comparison: under continuous attack by fumigation mist (SO₂ acidic gas + Cl⁻), film without M88 yellows and becomes brittle, while film containing M88 passivates and resists it, staying clear with its tensile strength intact.
Inhibits acidic gas degradation of PE chains
Effectively inhibits the degradation of PE polymer chains by the acidic gases produced when sulfur burns, preventing the film from rapidly embrittling and rupturing under frequent fumigation.
Resists chloride ion attack from irrigation water
Resists chloride ion attack volatilised from agricultural irrigation water, keeping the greenhouse film’s tensile strength and light transmittance in good condition.
MFI 20 · withstands 310℃ processing
With a melt flow index of 20 g/10min, flow and dispersion uniformity in greenhouse film production are excellent; it withstands processing temperatures up to 310℃, adapting to all kinds of blown-film and extrusion equipment with smooth forming and no gel spots.

Usage and processing recommendations
01Product positioning
M88 belongs to the "functional masterbatch" category; the official full name is "PE Sulfur-Chlorine Aging-Resistant Masterbatch M88", and it belongs to the functional masterbatch series. The handbook table-of-contents line, verbatim: "M88: PE Sulfur-Chlorine Aging-Resistant Masterbatch — improves the sulfur-chlorine aging resistance of PE agricultural films and greenhouse films"; the official tagline line takes the original sentence after the dash in the table-of-contents line, "improves the sulfur-chlorine aging resistance of PE agricultural films and greenhouse films". (Data source: product handbook / official product data)
[Product Overview] Technical section (targeted development statement): "Sulfur fumigation is a commonly used agricultural disinfection method that can be used to kill pathogens, insect eggs, and other pests in the soil. PE greenhouse agricultural films that have undergone sulfur fumigation are prone to acid aging, deformation, or breakage. Chlorides are usually present in agricultural irrigation water sources; when the water source contains chloride ions, as the temperature rises and they volatilize, they corrode greenhouse agricultural films and cause aging. ... improves the sulfur fumigation resistance and chlorine aging resistance of PE agricultural films." (Data source: product handbook / official product data)
Breakdown of the two terms in the functional direction (as per the source): ① Sulfur fumigation resistance — "PE greenhouse agricultural films that have undergone sulfur fumigation are prone to acid aging, deformation, or breakage"; ② Chlorine aging resistance — "when the water source contains chloride ions, as the temperature rises and they volatilize, they corrode greenhouse agricultural films and cause aging".

08FAQ
Is M88 a flame retardant masterbatch?
No. M88 is a PE sulfur/chlorine aging resistance masterbatch—its name, catalog line, overview, and specification table contain no flame retardant rating / flame retardant mechanism / UL94-type wording in any source; its functional direction is sulfur fumigation resistance + chlorine aging resistance.
How does it protect agricultural film?
It addresses two failure scenarios: ① it inhibits the degradation of PE polymer chains by the acidic gases produced by burning sulfur, preventing the agricultural film from rapidly embrittling and breaking due to frequent fumigation; ② it resists chloride ion attack volatilized from irrigation water, maintaining the greenhouse film's tensile strength and light transmittance. "Protects the physical and mechanical strength of agricultural film and extends its service life".
How much is added?
Internal addition ratio 2%-6% (denominator = total mass of the resin system); adjust according to target service life, film thickness, fumigation frequency and concentration; the specific ratio is determined by small-scale trials.
What processing temperature can it reach?
The handbook specification table states <310℃; the detail page states "can withstand processing temperatures up to 310℃, suitable for various blown film and extrusion equipment, smooth molding without particle spots"; the general rules require it not to exceed the maximum temperature recommended in the product brochure.
Is there quantitative data on the resistance?
No quantitative data is provided: the evaluation criteria for sulfur fumigation resistance / chlorine aging resistance (such as artificial accelerated aging duration, mechanical retention rate, yellowing index, etc.) are not documented for this grade, and this page does not extrapolate.
What are the packaging and storage conditions?
This grade's page does not list packaging, shelf life, or storage conditions—refer to the accompanying shipment information; moisture protection follows the series general rules (store remaining masterbatch sealed to prevent moisture). Each batch is accompanied by a COA test report.
