Lauryl myristyl alcohol ethoxylated 2 mol
Lauryl myristyl alcohol ethoxylate 2 mol is a nonionic surfactant chemical compound widely used in the cosmetics, detergents and textile industries. It is produced by the reaction between lauryl myristyl alcohol (a mixture of lauryl and myristyl fatty alcohols) and ethylene oxide (with an average ratio of 2 mol).
Lauryl alcohol ethoxylates are nonionic surfactants that are produced through the ethoxylation of lauryl alcohol. Lauryl alcohol, also known as dodecanol, is a fatty alcohol derived from natural sources such as coconut or palm kernel oil. The ethoxylation process involves reacting lauryl alcohol with ethylene oxide, resulting in the formation of lauryl alcohol ethoxylates. The number of ethylene oxide units added during ethoxylation can vary, leading to different grades of ethoxylates with distinct properties.

Linear Low Density Polyethylene (LLDPE)
LLDPE stands for Linear Low-Density Polyethylene. It is a type of polyethylene (a polymer made from ethylene monomers) that has short, linear branches in its molecular structure. This structure gives LLDPE unique properties compared to LDPE (Low-Density Polyethylene) and HDPE (High-Density Polyethylene).
StructureLLDPE has a unique linear molecular structure with short, controlled branches. This structure is different from LDPE (Low-Density Polyethylene), which has long and irregular branches. LLDPE consists of ethylene monomers (–CH₂–CH₂–) linked in a linear fashion. It has short, uniform side branches created by copolymerizing ethylene with α-olefins (like butene, hexene, or octene).These branches prevent the polymer chains from packing too tightly, giving LLDPE low density and flexibility.
PropertiesLLDPE (Linear Low-Density Polyethylene) is a versatile thermoplastic polymer known for its excellent flexibility, high impact resistance, and good tensile strength. it is slightly denser than LDPE but less rigid than HDPE, making it ideal for applications requiring toughness and stretchability. It has a high elongation at break (>500%), allowing it to withstand significant stretching without tearing. LLDPE exhibits excellent chemical resistance against acids, bases, and alcohols while maintaining low water absorption, making it suitable for moisture-sensitive applications. Thermally, it has a melting point of approximately 110–125°C and remains functional between -50°C and 60°C. Though it lacks inherent UV resistance, stabilizers can be added to improve durability under sunlight. Its ease of processing through extrusion, blow molding, and film manufacturing makes it widely used in plastic films, flexible tubing, cable insulation, and various molded products. While lldpe is non-biodegradable, it is recyclable, contributing to sustainable material management.

Low Density PolyEthylene (LDPE)
LDPE film
LDPE film grade is divided into several types, including general-purpose film, high-transparency film, heavy-duty film, shrink film, and cast film. These materials possess superior physical and mechanical properties, along with high chemical stability and excellent electrical insulation. They also feature low water vapor permeability and outstanding processability, making them ideal for various applications. Films made from these resins provide exceptional clarity and strong resistance to aging, ensuring durability and long-lasting performance.
StructureLDPE (Low-Density Polyethylene) film grade is a thermoplastic polymer made from ethylene monomers (C₂H₄) through a high-pressure polymerization process. Its molecular structure is characterized by high branching, which gives it its unique properties. Key Structural Features: Highly Branched Polymer:
- LDPE has short-chain and long-chain branches, preventing tight packing of polymer chains.
- Due to branching, LDPE has low crystallinity (~40–50%), making it soft and transparent.
- It is more flexible and stretchable than HDPE (High-Density Polyethylene).
- LDPE has a broad molecular weight distribution, contributing to good melt strength and processability in film extrusion.
PropertiesLow-Density Polyethylene (LDPE) film grade is a highly flexible and lightweight material known for its excellent elongation, impact resistance, and transparency. With a density ranging from 0.915 to 0.930 g/cm³, it offers good clarity but can appear slightly hazy. It has a relatively low melting point of around 105–115°C and remains flexible even at sub-zero temperatures, making it suitable for various applications. LDPE exhibits moderate tensile strength (8–17 MPa) and exceptional elongation at break (100–600%), ensuring durability and resilience. While it provides a good moisture barrier, its gas barrier properties are poor, allowing oxygen and CO₂ to pass through. Chemically, LDPE resists acids, bases, and alcohols but is vulnerable to hydrocarbons. Its excellent heat-sealing properties make it ideal for packaging applications, including food wrap, shrink films, and shopping bags. Additionally, it is widely used in agricultural films, protective industrial films, and medical applications such as IV bags and tubing. LDPE is typically processed through blown or cast film extrusion, operating within a temperature range of 160–220°C. However, due to its susceptibility to UV degradation, stabilizers are often added for outdoor applications. Overall, LDPE film grade is a versatile and cost-effective material, valued for its flexibility, sealability, and ease of processing.

Low Density PolyEthylene Injection (LDPE)
LDPE injection molding grade
LDPE injection molding grade is a specialized type of Low-Density Polyethylene designed for molding applications that require flexibility, impact resistance, and ease of processing.
StructureThe structure of LDPE injection molding grade is characterized by a highly branched, amorphous polymer configuration, which distinguishes it from other forms of polyethylene such as High-Density Polyethylene (HDPE). The polymer chains in LDPE are irregularly branched, meaning the chains do not pack closely together, resulting in a low degree of crystallinity. The polymerization of LDPE occurs through free-radical polymerization, typically under high pressure, which causes the long chains of the polymer to have side branches. For the injection molding grade, the polymer structure is tailored to achieve a higher melt flow index (MFI), which facilitates the material's smooth flow and filling into injection molds.
PropertiesLDPE injection molding grade is a versatile polymer characterized by its high degree of branching and amorphous structure, which results in excellent flexibility. This material ensures smooth and efficient flow during the injection molding process. This makes it suitable for producing intricate parts with good surface finish. LDPE injection molding grade exhibits moderate tensile strength (around 8-12 MPa) and excellent elongation at break, providing resistance to cracking and impact. The material is also known for its good chemical resistance, particularly against acids, bases, and alcohols, while being less resistant to hydrocarbons. Additionally, it offers low moisture absorption and performs well under low temperatures, maintaining its flexibility. LDPE is easy to process and heat sealable. Despite its high impact resistance and toughness, it has a relatively low stiffness compared to higher-density polyethylene grades.
