01 | Deconstruction of PC Resin Properties<\/span><\/h1>\n

 <\/p>\n

PC PK2870 is a high-viscosity blow-molded polycarbonate (pc resin) specifically developed for the food contact field. It adopts a branched molecular structure design and has comprehensive advantages such as high melt strength, excellent optical performance, and strong thermal stability. It is particularly suitable for the manufacturing of hollow products with dual requirements for transparency and structural strength.<\/span><\/p>\n

\u00a0 \u30fbMelt strength advantage:<\/strong> The branched structure significantly enhances the material's supporting capacity in a high-temperature molten state, effectively addressing common issues such as sagging and uneven wall thickness during blow molding. It is suitable for thin-walled molding and medium to large-sized bottle products.<\/span><\/p>\n

\u00a0 \u30fbOutstanding optical performance:<\/strong> The refractive index reaches 1.586, the light transmittance is 88%, and the haze is as low as 0.8%. The surface of the product has a natural luster and is visually transparent, meeting the strict requirements of high-end beverage packaging for \"appearance texture\".<\/span><\/p>\n

\u00a0 \u30fbStable mechanical properties:<\/strong> tensile strength of 70 MPa, flexural modulus of 2300 MPa, notched impact strength as high as 76.5 kJ\/m\u00b2, ensuring the reliability of the products in transportation, drop and other scenarios.<\/span><\/p>\n

\u00a0 \u30fbOutstanding heat resistance:<\/strong> The heat distortion temperature can reach up to 145\u00b0C, making it suitable for repeated hot drink brewing and high-temperature sterilization environments, thus expanding the practical application boundaries of food contact packaging.<\/span><\/p>\n

\u00a0 \u30fbSafety compliance certification:<\/strong> Complies with UL 94 HB flame retardant grade, supports RTI certification under different wall thicknesses, conforms to the food contact material regulations of the European Union and the United States, and is suitable for the global mainstream market.<\/span><\/p>\n

 <\/p>\n

02 | Main application scenarios<\/span><\/h2>\n

 <\/p>\n

The performance design of PC PK2870 fully considers the balance among transparency, security and processability. Its typical applications include:<\/span><\/p>\n

\u00a0 \u30fbHigh-transparency food containers:<\/strong> such as disposable or reusable beverage cups, sports water bottles, portable liquid storage tanks, etc.<\/span><\/p>\n

\u00a0 \u30fbTransparent industrial hollow parts:<\/strong> Suitable for industrial containers, window components, etc. that require both appearance transparency and structural strength.<\/span><\/p>\n

\u00a0 \u30fbMedical and laboratory consumables:<\/strong> such as culture flasks and reagent bottles, which require high material purity and stable blow molding performance.<\/span><\/p>\n

07 | Frequently Asked Questions (FAQ)<\/span><\/h2>\n

 <\/p>\n

Q1: What are the differences between PC PK2870 and traditional injection-grade PC resin?<\/span><\/strong><\/p>\n

A: PK2870 is a specially developed branched high-viscosity formula for blow molding scenarios, featuring high melt strength and the ability to withstand significant tension and thermal deformation during hollow molding. In contrast, injection-grade PC materials are mainly characterized by their high fluidity.<\/span><\/p>\n

Q2: Does this PC resin meet the food contact standards?<\/span><\/strong><\/p>\n

A: Yes, PC PK2870 complies with major food contact regulations such as FDA and EU No. 10\/2011, and can be safely applied in fields such as drinking water containers and beverage packaging.<\/span><\/p>\n

Q3: What are the key parameter suggestions during processing and forming?<\/span><\/strong><\/p>\n

A: It is recommended that the mold temperature be controlled at 80 to 100\u00b0C, and the temperature of the blow molding heating zone be set at 240 to 260\u00b0C. It is recommended to use medium and high-pressure blowing to ensure uniform wall thickness. Meanwhile, an appropriate cooling time is conducive to improving the transparency of the formed material.<\/span><\/p>\n
