Description<\/span><\/h2>\n<\/div>\n

The Highest-Volume Production Color<\/span><\/h3>\n

White is not a color choice, it is the default manufacturing state. The board is produced in continuous extrusion runs without stopping the line for color changeover. The result: the shortest lead time (7 to 14 days), the lowest MOQ (2 tons), the most consistent batch-to-batch quality, and the lowest per-sheet cost of any color.<\/p>\n

The L* 92 Substrate Standard<\/span><\/h3>\n

L above 92 is the printing industry’s substrate standard.* The CIE Lab* color space quantifies whiteness on the L* axis, 0 is perfect black, 100 is perfect diffuse white. A board at L* > 92 provides a near-neutral, high-reflectance substrate for color-accurate digital and screen printing. When a UV printer lays down CMYK ink, the unprinted areas are the board’s own white. If the board has a yellow or grey cast, L* below 90 is visually perceptible, the entire printed image shifts. A print shop that sends 500 signs to a customer measures its reputation by how clean the white looks against the customer’s expectation.<\/p>\n

Incidental Reflectivity From Titanium Dioxide<\/span><\/h3>\n

The titanium dioxide pigment used for whiteness also provides some incidental UV reflectivity.<\/strong> White boards reflect more solar radiation than colored boards, which helps keep the material cooler and reduces UV exposure in the surface layer. This effect is inherent to white pigmentation but does not replace a dedicated UV stabilizer package for outdoor applications.<\/p>\n

Cooler Panel Temperatures Outdoors<\/span><\/h3>\n

White reflects solar infrared, a thermal advantage outdoors.<\/strong> A white co-extruded board under direct summer sun stays 15 to 20\u00b0C cooler at the surface than a dark-colored board in the same location. The temperature difference matters: thermal expansion stress on the panel and its fasteners is reduced, UV degradation proceeds more slowly at lower temperatures, and the board surface stays further from its softening range. For outdoor architectural panels in hot climates, white can perform better than dark colors because it runs cooler and the installation design has less thermal movement to accommodate.<\/p>\n

Batch-to-Batch Color Consistency<\/span><\/h3>\n

White is not one white.<\/strong> TiO\u2082 grades from different suppliers, TiO\u2082 loading levels, stabilizer packages, and extrusion parameters produce subtly different whites. Two white boards from two manufacturers, both claiming L* > 92, can look different when placed side by side under D65 standard lighting, one may appear slightly blue-white, the other slightly warm-white. This is why batch-to-batch color consistency, quantified as \u0394E under D65 illumination, matters more than the absolute L* number. A board that is consistently L* = 91 with \u0394E < 1.0 across batches is functionally better for a sign maker than a board that varies between L* = 91 and L* = 94 with \u0394E = 3.0.<\/p>\n<\/div>\n<\/div>","protected":false},"excerpt":{"rendered":"

White PVC foam board is the highest-volume item on Shine production lines, run in continuous extrusion without color changeover. That continuity delivers the shortest lead times, the lowest per-sheet cost, and the most consistent batch quality.<\/p>\n

Whiteness is controlled to L* > 92, the printing industry’s substrate standard, with batch-to-batch matching against retained samples for repeat orders.<\/p>\n

White is also the most stable color outdoors, because it reflects solar radiation and runs cooler than dark panels.<\/p>\n<\/div>","protected":false},"featured_media":6613,"template":"","meta":{"_gspb_post_css":"","_crdt_document":"","_uag_custom_page_level_css":""},"product_brand":[],"product_cat":[17],"product_tag":[157],"class_list":["post-6739","product","type-product","status-publish","has-post-thumbnail","product_cat-pvc-foam-board","product_tag-color","first","instock","shipping-taxable","product-type-simple"],"uagb_featured_image_src":{"full":["https:\/\/www.shinepvc.com\/wp-content\/uploads\/2026\/08\/pvc-foam-board-white-01.webp",1000,1000,false],"thumbnail":["https:\/\/www.shinepvc.com\/wp-content\/uploads\/2026\/08\/pvc-foam-board-white-01-150x150.webp",150,150,true],"medium":["https:\/\/www.shinepvc.com\/wp-content\/uploads\/2026\/08\/pvc-foam-board-white-01-300x300.webp",300,300,true],"medium_large":["https:\/\/www.shinepvc.com\/wp-content\/uploads\/2026\/08\/pvc-foam-board-white-01-768x768.webp",768,768,true],"large":["https:\/\/www.shinepvc.com\/wp-content\/uploads\/2026\/08\/pvc-foam-board-white-01.webp",1000,1000,false],"1536x1536":["https:\/\/www.shinepvc.com\/wp-content\/uploads\/2026\/08\/pvc-foam-board-white-01.webp",1000,1000,false],"2048x2048":["https:\/\/www.shinepvc.com\/wp-content\/uploads\/2026\/08\/pvc-foam-board-white-01.webp",1000,1000,false],"trp-custom-language-flag":["https:\/\/www.shinepvc.com\/wp-content\/uploads\/2026\/08\/pvc-foam-board-white-01.webp",12,12,false],"woocommerce_archive_thumbnail":["https:\/\/www.shinepvc.com\/wp-content\/uploads\/2026\/08\/pvc-foam-board-white-01-500x500.webp",500,500,true],"woocommerce_thumbnail":["https:\/\/www.shinepvc.com\/wp-content\/uploads\/2026\/08\/pvc-foam-board-white-01-300x300.webp",300,300,true],"woocommerce_single":["https:\/\/www.shinepvc.com\/wp-content\/uploads\/2026\/08\/pvc-foam-board-white-01-300x300.webp",300,300,true],"woocommerce_gallery_thumbnail":["https:\/\/www.shinepvc.com\/wp-content\/uploads\/2026\/08\/pvc-foam-board-white-01-100x100.webp",100,100,true]},"uagb_author_info":{"display_name":"Yuzhi","author_link":"https:\/\/www.shinepvc.com\/ko\/author\/"},"uagb_comment_info":0,"uagb_excerpt":"White PVC foam board is the highest-volume item on Shine production lines, run in continuous extrusion without color changeover.
