LG Lupoy HP100S is a compounded ABS grade optimized by LG Chem for sheet extrusion. The older HP100 was purely an injection‑molding grade. Fabricators reported insufficient melt strength when trying to run HP100 for continuous sheet extrusion. LG Chem adjusted rubber phase composition and molecular‑weight distribution and launched HP100S, the "S" standing for sheet modification. This revised grade works reliably for both injection and extrusion processes.
This resin has been widely traded across Asia‑Pacific and South‑American markets. Sheet producers frequently select it as a drop‑in replacement for Taita1000. Buyers often compare HP100, HP100S, Ineos HI‑10 and Tianjin Dagu MG29 during material selection. HP100S delivers solid performance on both Izod and Charpy impact under ASTM and ISO test standards. Its balanced mechanical properties support tough thick‑wall injection parts as well as continuous extruded sheet production.

Main Product Advantages
HP100S stands out for its well‑balanced melt strength and toughness. High‑rubber formulation delivers consistent impact resistance and reduces stress‑whitening on thick‑wall articles. Good elongation‑at‑break prevents sheet tearing and sagging at the die during extrusion, granting a broad processing window and good compatibility with most extruder screws and die designs.
Natural pellets show good whiteness and provide reliable adhesion for subsequent painting, hot‑stamping and printing. It also offers decent creep‑resistance to limit deformation under long‑term load.
Known limitations: Medium‑range flow property makes it unsuitable for ultra‑thin‑wall complex components. No weather‑resistant modification is built‑in; unprotected outdoor exposure will cause rapid yellowing and ageing.
Typical Applications
Extrusion: ABS decorative sheet, refrigerator liner sheet, thermoforming substrate, building‑profile extruded parts
Injection molding: Safety helmets, tool cases, power‑tool housings, thick‑wall home‑appliance covers, thick automotive interior components
Processing Guidance
This grade supports both injection and extrusion. For sheet extrusion, strict pre‑drying is mandatory. Avoid excessive screw speed to prevent material shear degradation. For injection molding, target thick‑wall large‑size articles; do not specify it for thin‑wall intricate parts.
Important note: Some resins list only injection‑molding parameters on TDS even with similar melt index. Do not force‑fit those grades into sheet‑extrusion production.
Custom Options
Natural pellets are standard supply. Black and other solid colors are available subject to LG Chem production scheduling minimums. Compounding modification such as extra toughening or flame retardancy is not offered for this base grade; please refer to dedicated modified series for those requirements. COA and MSDS documents can be provided. For shipments to Ecuador, we can issue FORM‑R certificate under China‑Ecuador FTA for import‑tariff reduction.
Packaging
Standard packing: 25 kg laminated kraft paper bags, sealed for moisture‑proof and light‑shield storage. 1000 kg big‑bag option is available for automated factory feeding. Full container shipments use pallets with stretch‑wrapping to minimise bag damage during ocean transit.
Comparable Grades
1. Taita TAITALAC‑1000: Closest match, dual‑purpose for injection & extrusion. Near‑identical sheet‑processing settings. HP100S delivers slightly better low‑temperature toughness and more stable global supply. Some existing customers are used to Taita's surface gloss and minor masterbatch tuning may be needed.
2. Ineos HI‑10: Dual‑purpose grade with superior low‑temperature impact. Lower melt‑flow leads to higher extrusion torque; equipment adjustment is required for regular sheet runs. Usually higher material cost than HP100S.
3. LG HP100: Older sibling grade, injection‑only. Higher melt‑flow for fast cavity filling, lacking the melt‑strength critical for sheet extrusion.
4. Chimei PA‑749K: High‑impact injection‑focused ABS. It can barely run thin sheet extrusion yet performs poorly for thick sheet. Good room‑temperature impact but weak low‑temperature performance.
5. Tianjin Dagu MG29: Cost‑effective domestic high‑impact injection‑only resin. Insufficient elongation‑at‑break, not qualified for sheet extrusion.
6. Ineos Terluran EGP‑7: Second‑closest dual‑purpose extrusion‑injection grade, developed for sheet and thermoforming substrates. MFR 6.5 g/10 min. EGP‑7 gives better melt‑strength and anti‑sagging performance for heavy‑gauge sheet, yet costs more. Lower flow makes thick‑part injection filling harder, so it is not the first pick for cost‑sensitive projects.
7. Zhejiang Petrochemical ZA0211: Domestic alternative mainly for injection. Less stable sheet‑extrusion performance, fit for cost‑driven injection‑only orders.
Pros & Cons When Replacing Above Grades with HP100S
‑ Replace Taita1000: Plus: broader global supply chain, flexible stock allocation for South‑America. Minus: gloss difference may need minor masterbatch fine‑tuning for end‑users accustomed to Taita.
‑ Replace Ineos HI‑10: Plus: better flow, lower processing torque and competitive purchase cost. Minus: inferior ultra‑low‑temperature impact performance.
‑ Replace HP100: Plus: enables stable sheet extrusion. Minus: reduced flow; less ideal for thin‑wall injection filling.
‑ Replace PA‑749K: Plus: capable of stable sheet extrusion. Minus: slightly higher unit price, limited cost‑edge for pure‑injection jobs.
‑ Replace Tianjin Dagu MG29: Plus: extrusion‑ready, improved overall toughness especially at low temperature. Minus: higher procurement cost with no advantage for injection‑only applications.
‑ Replace ZA0211 / Yulong YL2020: Plus: proven extrusion performance and consistent batch‑to‑batch quality. Minus: higher price versus domestic resins; cost pressure for tight‑margin projects.
China‑Origin ABS vs North‑American / South‑American Sources for Ecuador Market
Since China‑Ecuador FTA took effect, Chinese plastic raw materials enjoy preferential tariff treatment with FORM‑R certificate, an advantage unavailable for North‑American and local South‑American suppliers.
Strengths of Chinese supply
1. FTA tariff relief lowers landed cost.
2. Wide grade portfolio including LG and domestic petrochemical resins; flexible mixed‑loading for consolidation shipments.
3. Responsive supply chain; small‑volume trial orders are well‑supported.
Weaknesses of Chinese supply
Ocean transit to Guayaquil runs 28‑35 days, longer than land‑based local delivery from North / South America. Robust moisture‑proof packaging is essential against ocean‑humidity risk. USD‑quoted prices are subject to exchange‑rate fluctuation.
North‑American sources**: Fast lead‑time, yet no FTA tariff benefit leads to higher overall landed cost. Resin grades follow local specs and sometimes show poorer compatibility with Asian‑origin processing equipment.
Local South‑American ABS**: Short delivery cycle. However frequent plant shutdowns cause erratic supply and sharp price jumps, with limited grade choices.
For sheet‑makers in Ecuador running medium‑to‑long‑term procurement plans, China‑sourced resins deliver stronger overall value. Local regional stock is more suitable for urgent small‑batch replenishment.
MOQ & Lead Time

FAQ
Q1: Can I substitute HP100S with HP100 for sheet extrusion?
A: Not recommended. HP100 is injection‑only without sufficient melt‑strength for sheet production. You will see sagging, wavy surface and high scrap rate.
Q2: Can I directly convert Charpy and Izod impact figures for comparison?
A: Direct conversion is not feasible. Specimen clamping methods differ between these two test standards. Always verify the test standard on datasheets during material evaluation.
Q3: Is FORM‑R mandatory for exporting to Ecuador?
A: FORM‑R is required if you wish to claim FTA preferential tariff reduction. Without it, general import‑duty rates will apply.
Q4: Can HP100S be used outdoors as‑is?
A: Natural HP100S contains no weather‑resistant additive. Outdoor service needs modification or surface‑coating protection.
Q5: What causes bubbles in extruded ABS sheet?
A: Inadequate pre‑drying is the most common root cause. ABS resin absorbs moisture easily; insufficient drying creates bubbles and silver marks in finished sheet.
