What types of specialty polymer materials does Sunrise Galaxy manufacture?
We manufacture 8 core series of specialty polymer materials: APAO Hot Melt Base Resins, Metallocene Polyolefin Modifiers, Moisture-Curable Polyisobutylene (SIPIB), Grafted Polyolefin Materials (MAH-g-POE, MAH-g-PP, MAH-g-PE), Cable Water-Blocking Compounds, Silane-Modified Polyolefin Systems, Reactive Polyisobutylene Derivatives and High-Performance Polyolefin Wax Modifiers. We currently offer 100+ standard product grades within these 8 series. A complete product catalogue is available on request.
What industries do your products serve?
Our materials are used across a wide range of industrial manufacturing sectors, including: Wire & Cable (semiconductive compounds, water-blocking, insulation modification), Automotive (adhesive systems, rubber modification, underbody coatings), Solar Energy (PV encapsulant film, edge tape adhesive), Construction & Waterproofing (SIPIB-based sealants, bitumen modification), Woodworking & Furniture (APAO hot melt edge banding), Flexible Packaging (heat seal layers, tie layers), Road Marking (hot melt road marking binder systems) and Industrial Adhesives & Sealants.
How do I select the right product grade for my application?
The best way to begin is to send us your application description — including substrate materials, processing temperature, performance requirements and any compliance constraints. Our technical team will review your application and recommend the most suitable grade from our standard product range, or advise whether a custom formulation would better meet your requirements. You can submit your technical inquiry via our Contact page or by email to our technical team directly.
What is APAO and what are its main industrial applications?
APAO stands for Amorphous Poly Alpha Olefin. It is a family of amorphous thermoplastic polyolefin resins produced by Ziegler-Natta polymerization of alpha-olefin monomers. APAO resins are characterized by excellent adhesion to a wide range of substrates, low melting viscosity, good flexibility and strong compatibility with other polymers and additives. Primary applications include hot melt adhesive base resins for edge banding, bookbinding, packaging and assembly adhesives, as well as bitumen modification for road paving and waterproof membrane systems.
What is SIPIB and why is it unique?
SIPIB stands for Silane-terminated mid-molecular-weight Polyisobutylene. It is a moisture-curable reactive polymer technology developed and patented by our R&D team — making us the world’s first and currently only commercial-scale manufacturer of this specific product class. SIPIB crosslinks at room temperature upon exposure to atmospheric moisture, forming a flexible, permanently elastic, excellent waterproof polymer network. It is used as the core polymer in premium sealant formulations, particularly in construction joint sealing, façade applications and insulating glass secondary sealant systems where low gas permeability and high long-term durability are required.
What molecular weight ranges are available for your PIB products?
We offer Polyisobutylene (PIB) and reactive PIB derivatives across a broad molecular weight spectrum. Our standard PIB range covers Mn from approximately 500 to 100,000 Daltons. Our SIPIB products are specifically designed in the mid-molecular-weight range of Mn 4,000 to 20,000, which is the optimal range for achieving the balance between processability and crosslinked network performance in sealant applications. Custom molecular weight specifications outside our standard range can be discussed with our technical team for dedicated production runs.
Do your APAO products comply with food contact or medical application requirements?
Certain grades within our APAO range are produced from monomers and with catalysts that may be suitable for food contact applications subject to the specific applicable regulation in your target market (e.g., FDA 21 CFR, EU Regulation No. 10/2011). However, formal food contact compliance must be evaluated on a grade-by-grade and application-by-application basis. Please contact our technical team with your specific application requirements and target market, and we will provide the relevant documentation and regulatory assessment for the grade(s) under consideration.
What is the softening point range for your hot melt APAO resins?
Our APAO hot melt base resins are available in softening point ranges from approximately 85°C to 160°C (Ring & Ball method), depending on the specific grade and polymer composition. Lower softening point grades are typically used in open-time sensitive assembly applications, while higher softening point grades are preferred for high-temperature-resistant packaging or road marking applications. A full technical datasheet showing softening point, melt viscosity, molecular weight distribution and other key parameters is available for every standard grade.
Can your products be used in combination with each other — for example blending APAO with PIB?
Yes. Many of our customers formulate blended systems using multiple components from our product range. APAO and PIB blends are a well-established formulation approach in pressure-sensitive adhesive and sealant applications. We can advise on compatibility, recommended blend ratios and expected performance outcomes based on your target application. Our technical team can also provide sample blending guidance and assist with lab evaluation of blend properties.
Do you have technical datasheets available for all your products?
Yes. A complete Technical Data Sheet (TDS) is available for every standard product grade we manufacture. TDS documents include: product description, chemical composition basis, key physical and performance specifications (softening point, melt viscosity, molecular weight, density, colour), recommended processing conditions and primary application guidance. SDS (Safety Data Sheets) and COA (Certificate of Analysis) are also available on request for all grades. You can request documentation through our Contact page or directly by email.
