LS-944 (High Molecular Weight HALS) was traditionally mainly used in PP/PE agricultural films, injection molded parts and PVC profiles; its application structure has now undergone obvious changes:
Photovoltaics (backsheets, EVA adhesive films, frames): Annual growth rate over 22%, with extremely high requirements for high-temperature weather resistance and low precipitation.
Automobiles (exterior parts, bumpers, battery pack housings): Global penetration rate rising from 18% to 35%, directly replacing low-molecular-weight 770/622.
Outdoor building materials (profiles, guardrails, roofing materials): Driven by EU REACH and carbon tax, low VOC, low migration and long-term stability have become standard configurations.
Traditional agricultural films/packaging: Demand remains flat or slightly declining, with rigid demand for low-cost general-grade LS-944.
One-sentence summary: Low-end market stable, high-end market explosive growth; weather resistance and new energy become growth engines.
Global effective capacity: China 65%, BASF (Germany/USA) 20%, Japan and South Korea 10%, others 5%.
General grade (98–99%): Overcapacity in China (Lianlong, Fengguang and other additive manufacturers) with fierce price wars (58–65 RMB/kg).
High-end weather-resistant grade (99.5%+, low VOC, low precipitation, thermal stability > 270℃): Monopolized by BASF, Songwon and ADEKA with a 30–50% premium and delivery cycles of 4–8 weeks.
New overseas capacity: Small-scale projects under construction in the Middle East and Southeast Asia will be released after 2028, unable to shake the market pattern in the short term.
One-sentence summary: Fierce price competition in Chinese low-end market, high-end market controlled by foreign capital; global supply presents a dumbbell-shaped differentiation.
EU REACH, SVHC and RoHS restrict low-molecular impurities, VOC and heavy metals, mandating high purity, low migration and traceable COA.
Carbon Border Adjustment Mechanism (CBAM), North American EPA and Japanese Chemical Review Law raise standards for production energy consumption, emissions and wastewater, accelerating the phase-out of old high-pollution facilities.
End-brand manufacturers (Tesla, BYD, LONGi, BASF system) directly require ISO 14001, REACH registration, batch traceability and 90-day safety inventory.
One-sentence summary: Non-compliance means no orders; green compliance has upgraded from an advantage to a mandatory requirement.
Core raw materials TMP/piperidinol: Price increased by 40–60% in 2025–2025 due to caprolactam industrial chain fluctuations, squeezing the gross profit margin of general grade to 10–15%.
High-end grade: Supported by foreign capital control and certification barriers, prices remain firm and upward with a gross profit margin of 35–45%.
Regional price gaps widen: Europe > North America > Japan and South Korea > Domestic China, creating obvious arbitrage space for global procurement.
Shipping & energy: Red Sea crisis and natural gas price hikes drive international logistics costs up by 25% and extend delivery cycles.
One-sentence summary: Low-end thin profit margins, high-end premium profits; cost pressure concentrates upstream and transmits downstream.
European and American customers take the initiative to reduce reliance on China: Certify local capacity of BASF, Japan-South Korea and Thailand simultaneously to build 2–3 supply sources.
Leading Chinese enterprises go global: Lianlong and other manufacturers build factories in Southeast Asia to serve global customers and avoid tariff and compliance risks.
Combination of long-term contracts and spot goods becomes mainstream: 60–70% locked by long-term contracts for price and volume, 30% purchased via spot transactions for flexible inventory replenishment.
Technology service binding: High-end buyers demand formula collaboration, testing support and customized specifications; pure product sales face survival pressure.
One-sentence summary: Safety first, diversified sourcing dominates; supply chain shifts from cost orientation to resilience and technology orientation.
HiSiaddi divides downstream buyers into four typical categories covering global B-end clients:
General plastic modification/injection molding factories (China, Southeast Asia, Middle East, South America globally)
Photovoltaic material manufacturers (China, Europe, North America, Japan and South Korea globally)
Automotive interior/exterior parts & battery pack manufacturers (Europe, America, Japan-South Korea, China globally)
Outdoor building materials/coating factories (Europe, America, Asia-Pacific globally)
Raw material price hikes drive up LS-944 costs, while end-product prices are rigid, squeezing gross profit margins to 5–8%.
Numerous general-grade suppliers with uneven quality lead to large batch differences in chromatic aberration, thermal stability and precipitation, resulting in high product scrap rates.
Tightening environmental compliance raises low VOC and REACH requirements, increasing certification and testing costs and bringing heavy pressure on small and medium-sized factories.
Global general-grade capacity concentrates in China with sufficient spot supply and low prices, enabling global price comparison to cut costs.
Replace low-molecular-weight HALS (770/622): LS-944 features long service life, low migration and better temperature resistance, improving product competitiveness with a 5–10% premium.
Phase out low-price and low-quality suppliers, lock 2–3 stable general-grade suppliers, and sign long-term contracts to stabilize prices and supply amid market fluctuations.
Global shortage of high-end weather-resistant LS-944 (99.5%+, low VOC, thermal stability > 270℃), controlled by foreign capital with delivery cycles of 4–8 weeks and high prices.
Extremely high certification thresholds: REACH, ISO, photovoltaic industry standards (IEC 61730), batch traceability and low precipitation testing, which small and medium-sized suppliers cannot pass.
High sensitivity to purity, moisture, volatile matter and metal ions; batch fluctuations directly cause photovoltaic backsheet yellowing, adhesive film aging and module failure with huge losses.
Photovoltaics is the fastest-growing track for LS-944 with an annual growth rate over 22%, featuring strong long-term demand certainty and willingness to pay premium prices for stable quality.
Amid global supply chain restructuring, European and American photovoltaic customers actively seek second-source suppliers outside BASF, creating great opportunities for high-quality domestic high-end suppliers.
Carry out joint R&D of special photovoltaic specifications with leading suppliers to lock priority supply rights for 2–3 years and secure production capacity and technological advantages.
Stringent automotive-grade standards (OEM specifications, VOC, odor, fogging, weather resistance testing) with a certification cycle of 6–12 months and high costs.
Battery pack housings have high requirements for high temperature resistance, low precipitation and flame retardant synergy, resulting in few qualified suppliers and unstable delivery.
Strict cost control by vehicle manufacturers demands both high quality and cost reduction, bringing heavy bargaining pressure.
Automotive lightweighting and new energy transformation create huge space for LS-944 to replace low-molecular-weight HALS, with rapidly rising global penetration rate.
Global automotive capacity transfer to Asia enables Japan-South Korea and China dual-source procurement to balance quality, price and supply risks.

Strict EU REACH and North American environmental standards make low VOC, low migration and long-term weather resistance standard configurations with high certification costs.
Diverse specifications and small batches of building materials/coatings require customized formulas, demanding high supplier flexibility and technical service capabilities.
Fierce market price competition compresses the premium space of high-end products, bringing heavy cost control pressure.
Outdoor building materials require a service life of 10–20 years; LS-944 boasts obvious advantages in long-term weather resistance, yellowing resistance and chalking resistance, improving product competitiveness with a 10–15% premium.
