I.Application Field

  1. Plastic industry:

    • For rigid plastics such as PVC, PS, ABS, etc., a   fluorescent whitening agent OB-1 with good heat resistance and low    migration should be selected. Because rigid plastics usually require higher temperatures during processing, the heat resistance of OB-1 can   ensure that it will not decompose or change color at high temperatures.

    • For soft plastics such as PE, PP, etc., the   compatibility of the whitening agent with the plastic should be considered. OB-1 should be evenly dispersed in soft plastics without agglomeration or precipitation to ensure the appearance quality of      plastic products.

    • At the same time, the influence of OB1 on the fluidity and printing performance of inks should be considered

II.Performance Indicators

  1. Whitening effect:

    • This is one of the key indicators for choosing   fluorescent whitening agent OB-1. Different brands or models of OB-1 can     be compared under the same application conditions to select the one with      better whitening effect. Generally speaking, the better the whitening effect, the higher the appearance quality of the product.

    • Professional instruments such as colorimeters      and whiteness meters can be used to measure the whiteness value of the      product to objectively evaluate the whitening effect of OB-1.

  2. Heat resistance:

    • If the application field requires processing or   use at higher temperatures, such as plastic injection molding, coating      baking, etc., an OB-1 with good heat resistance should be selected. Theheat stability can be evaluated by heat stability tests, that is,     observing the color change and performance loss of the whitening agent   after heating at different temperatures for a certain period of time.

III.Safety

  1. Environmental protection:

    • Select a fluorescent whitening agent OB-1 that      meets environmental protection requirements and avoid using products      containing harmful substances or causing pollution to the environment.      Environmental certification marks such as RoHS certification and REACH      certification can be checked.

    • Understand whether the production process of the      whitening agent complies with environmental protection standards and      whether green production processes are adopted.

  2. Safety:

    • For products that may come into contact with the      human body, such as plastic products and textiles, a safe OB-1 should be      selected. The safety data sheet (SDS) of the product can be checked to      understand its potential harm to the human body and safe use methods.

    • Ensure that the whitening agent will not release      harmful substances during use and will not affect human health.

IV.Supplier Selection



  1. Reputation and word-of-mouth:

    • Select a supplier with good reputation and      word-of-mouth. The product quality and service level of the supplier can      be understood by referring to supplier evaluations and customer feedback.

    • Consult enterprises or professionals in the same      industry to understand their evaluations and recommendations for      different suppliers.

  2. Technical support:

    • The supplier should be able to provide      professional technical support, including guidance on product selection,      use methods, and problem-solving.

    • Communicate with the supplier's technical      personnel to understand their professional knowledge and experience in      fluorescent whitening agent OB-1.

  3. Price and cost performance:

    • Price is an important factor in choosing a      supplier, but it cannot be solely price-oriented. The quality,      performance, service and other factors of the product should be      comprehensively considered to select a fluorescent whitening agent OB-1      with high cost performance.

    • Compare with multiple suppliers to obtain      different quotations and solutions for a wiser choice.

In conclusion, choosing theappropriate fluorescent whitening agent OB-1 requires comprehensiveconsideration of multiple factors such as application fields, performanceindicators, safety, and suppliers. Through careful comparison and evaluation, ahigh-quality whitening agent that meets the needs can be selected to improvethe quality and market competitiveness of products.
